DAW Recording
Digital Audio Workstations (DAWs) are software applications that have revolutionized the way that music is made. However, we cannot have a conversation about DAWs without discussing computer hardware, audio interfaces, and a few technical items along the way. For example, when choosing a computer for recording, there are several options to consider, such as PCs, Macs, and iPads, each with its own strengths and weaknesses. Additionally, computer audio interfaces are crucial piece of hardware that connects a computer to other audio equipment and converts analog signals to digital signals that the computer can process. Latency is also a common issue when recording, which can be reduced by adjusting the buffer size in the DAW or by using an audio interface with onboard DSP. Other technical aspects, such as sample rate, bit depth, recording levels, and gain-staging, are also important to consider when recording and producing digital audio.
Computer Recording
PCs vs Macs vs iPad
In order to use a DAW, a computer is required as it is the software that runs the DAW. The computer processes the audio data and runs the software, allowing users to record, edit, and produce digital audio. Additionally, a computer is necessary to connect to other audio equipment and to store and manage large amounts of audio data. While there are other options, such as using an iPad, a computer is generally the most practical and versatile option for recording and producing digital audio with a DAW.
When it comes to choosing a computer for recording, there are several options to consider. For PCs, both desktops and laptops are available, each with their own set of strengths and weaknesses. Desktops offer more power and flexibility for upgrading hardware, but they are not as portable as laptops. Laptops, on the other hand, are more portable, but they may not have as much processing power as desktops.
For Macs, there are also both desktops and laptops available. Like PCs, desktops offer more power and flexibility but are less portable, while laptops are more portable but may not have as much processing power. Apple has several choices for both desktops and laptops, including the Mac Pro, Mac Studio, Macbook Air, iMac, Mac mini, and MacBook Pro. The Mac Pro is a high-end desktop computer designed for professionals who need maximum processing power, while the Mac Studio is an all-in-one desktop with a built-in display. The MacBook Air is a lightweight and portable laptop, while the MacBook Pro is a more powerful laptop designed for professionals. The iMac is an all-in-one desktop with a built-in display, and the Mac mini is a compact desktop computer that can be used with any display.
In terms of audio interfaces, both PCs and Macs are compatible with a wide range of audio interfaces from various manufacturers, including Focusrite, PreSonus, MOTU, RME, and Apogee, among others. When choosing an audio interface, it’s important to consider factors such as the number of inputs and outputs, the quality of the ADC and DAC, and the type of connection (e.g. FireWire, USB, Thunderbolt).
Overall, whether you choose a PC or a Mac, desktop or laptop, or a specific audio interface, the key is to find the combination of hardware and software that best meets your needs and budget.
iPads are a relatively new option for recording, but they are becoming increasingly popular because of their portability and ease of use. They are particularly useful for recording on the go or for quick demos.
Computer Audio Interfaces
A computer audio interface is a piece of hardware that connects a computer to other audio equipment, such as microphones, instruments, and speakers. It converts analog audio signals to digital signals that can be processed by the computer and vice versa.
ADC and DAC: Why it matters
The quality of an audio interface is determined by its analog-to-digital converter (ADC) and digital-to-analog converter (DAC). The ADC converts analog audio signals to digital signals, while the DAC converts digital signals back to analog signals.

Latency
Latency is the delay between when a sound is produced and when it is heard through the speakers. It is caused by the time it takes for the computer to process the audio data. Latency can be a problem when recording because it can make it difficult to play along with a pre-recorded track or make precise edits.
Latency can cause problems for singers as well, particularly when recording vocals. When a singer hears a delay between their voice and the music in their headphones, it can be disorienting and make it difficult to stay on pitch. This is because the singer is hearing their voice in a different context than they are used to, which can throw off their sense of timing and pitch. Additionally, if the latency is too high, it can make it difficult to sing in time with the music, which can result in a sloppy or disjointed performance. To avoid these issues, it’s important to keep latency as low as possible when recording vocals and to use low-latency monitoring if available.
How can it be resolved?
Latency can be reduced in a number of ways. One method is by adjusting the buffer size in the DAW, but this may require some experimentation to find the optimal setting. Another option is to use an audio interface with onboard DSP, which can help to offload some of the processing power from the computer and reduce overall latency. Additionally, a variety of software tools available can help diagnose and mitigate latency issues, such as latency monitoring plugins and system optimization tools. Finally, it’s worth noting that the source of latency can sometimes be external to the computer or audio interface, such as with network latency or other hardware issues, so it’s important to consider all possible factors when troubleshooting latency problems.
Onboard DSP
Onboard DSP, or digital signal processing, is a feature that can be found on certain audio interfaces. This feature allows the interface to process audio data internally rather than relying on the computer’s processor to do so. This can be a major advantage, especially for those who are looking to reduce latency and improve overall performance. When a computer is processing large amounts of audio data, it can sometimes become bogged down, which can lead to a decrease in performance. By using onboard DSP, the audio interface can handle the processing of the audio data, freeing up the computer’s resources. This can help ensure that the audio remains crisp and clear without any lag or distortion. In addition, onboard DSP can also provide users with a variety of different effects and filters that can be applied to their audio in real-time. This can be particularly useful for musicians and podcasters who are looking to enhance their sound or for those who want to experiment with different effects. Overall, onboard DSP is a powerful feature that can significantly improve the quality and performance of your audio interface.
FireWire vs USB vs Thunderbolt
There are several types of computer ports that can be used to connect audio interfaces. These include FireWire, USB C, USB 2, USB 3, Thunderbolt 2, Thunderbolt 3, FireWire 800, and FireWire 400.

How do DAWs help with latency issues?
Digital audio workstations (DAWs) are an essential tool in the music production process. They provide a wide range of features that can help reduce latency, maintaining synchronicity between tracks and ensuring that they are recorded and played back without any noticeable delay. One of these features is the low-latency monitoring, which enables users to monitor their input signal with little to no delay, thus allowing them to effectively adjust and refine their recording as they go. Additionally, DAWs also offer automatic delay compensation, ensuring that the timing of recorded tracks is adjusted to compensate for any latency that may occur. By providing these features, DAWs make it possible for recording artists and producers to achieve the highest level of accuracy and precision in their audio work, without any compromise to the quality of the final recording.
What is Sample Rate?
Sample rate is the number of samples of audio data that are captured per second. It is measured in Hertz (Hz). Higher sample rates can result in higher quality audio, but they also require more storage space and processing power.
Is higher better?
Higher sample rates can indeed improve the quality of the audio, but they come at a cost. By capturing more data, they require more storage space and can also put a strain on processing power. However, it’s important to note that sometimes the increase in quality may not be noticeable to the human ear, especially if the audio is intended for casual listening. In other cases, the trade-off between quality and storage space may be worth it, such as when producing professional-grade audio for the film or music industry. Therefore, it’s crucial to carefully consider the intended use of the audio and the available resources before deciding on the appropriate sample rate.
Pros and Cons of higher sample rates
Pros:
- Higher quality audio: High sample rates allow for more detailed and accurate sound reproduction. This can result in a more immersive listening experience, especially when it comes to high-frequency sounds like cymbals, hi-hats, and vocal sibilance. Additionally, high sample rates can provide more headroom, allowing for greater dynamic range and reduced clipping.
- Greater dynamic range: With a higher sample rate, the dynamic range of audio is increased. This means that the difference between the quietest and loudest parts of a piece of music or a sound effect is more pronounced, resulting in a more dynamic and impactful listening experience.
- Reduced distortion: High sample rates can help reduce distortion, particularly in the high frequencies. This can lead to a cleaner and more accurate sound.
Cons:
- More storage space required: High sample rates require more storage space to store audio files. This can be a concern for those with limited storage space on their devices.
- More processing power required: To play back high sample rate audio, more processing power is required. This can be a concern for older or less powerful devices, which may struggle to play back high sample rate audio without dropping frames or buffering.
- Not all hardware supports high sample rates: Some hardware, particularly older or budget devices, may not support high sample rates. This can limit the availability and accessibility of high sample rate audio content.
List of typical sample rates
- Sample rates are the number of audio data samples captured per second, measured in Hertz (Hz). There are several common sample rates, including:
- 44.1 kHz: This is the standard sample rate used for CDs and is widely supported by most digital audio equipment. It provides a good balance between audio quality and storage space.
- 48 kHz: This is the standard sample rate used for digital video and is also commonly used in music production. It provides higher quality audio compared to 44.1 kHz but requires slightly more storage space.
- 88.2 kHz: This sample rate is used for high-quality audio production when higher frequencies need to be captured and is commonly used in classical music and film scoring.
- 96 kHz: This sample rate is commonly used for high-quality audio production when capturing a wide frequency range and is commonly used in music production and film scoring.
- 176.4 kHz: This sample rate is used for ultra-high-quality audio production when capturing the entire audible range of frequencies and is commonly used in classical music and film scoring.
- 192 kHz: This sample rate is used for ultra-high-quality audio production when capturing the entire audible range of frequencies and is commonly used in music production and film scoring.
The choice of sample rate ultimately depends on the intended use of the audio. For casual listening or streaming, a lower sample rate such as 44.1 kHz or 48 kHz is sufficient and requires less storage space. For professional audio production, a higher sample rate such as 96 kHz or 192 kHz may be necessary to capture the full range of frequencies and provide the highest possible quality. In addition, higher sample rates can be particularly important for music with high-frequency content, such as classical music and film scoring. However, it’s important to note that higher sample rates also require more processing power and storage space, which can be a concern for older or less powerful devices.
What is Bit Depth?
Bit depth refers to the number of bits used to represent each sample of audio data. It determines the dynamic range of the audio, or the difference between the loudest and softest sounds that can be represented.
The bit depth affects the quality of the audio file, as it determines the level of detail that can be captured in each sample. Higher bit depths can capture more detail, resulting in a more accurate representation of the original sound. However, this also means that the file size will be larger, as more data needs to be stored for each sample.
In addition, the bit depth can also affect the processing power required to work with audio files. Higher bit depths require more processing power, which can be a limiting factor for some devices or software.
Choosing the appropriate bit depth for your audio file depends on your specific needs and the intended use of the file. For high-quality recordings or professional use, a higher bit depth is typically recommended, while for casual listening or sharing, a lower bit depth may be sufficient.
Recording Levels
Recording levels are an essential part of any audio engineering setup. They refer to the amplitude or loudness of the audio signal being recorded, and they have a direct impact on the overall quality and clarity of the final product. There are several different types of recording levels used in audio engineering, each with its own advantages and disadvantages.
The first type of recording level is analog recording levels. Analog recording levels are the levels at which the analog audio signal is recorded on tape or other analog media. Analog recording levels are typically measured in decibels (dB) and are often referred to as VU (Volume Unit) or dBu (decibels relative to 0.775 volts) levels. Analog recording levels are important because they determine the amount of headroom available in the recording. Headroom is the amount of space between the highest level of the audio signal and 0dB. Headroom is important because it allows for any unexpected peaks in the audio signal to be accommodated without clipping or distortion.
The second type of recording level is digital recording levels. Digital recording levels are the levels at which the digital audio signal is recorded in the DAW or other digital media. Digital recording levels are typically measured in decibels relative to Full Scale (dBFS), which is the maximum level that can be recorded in the digital domain. Unlike analog recording levels, digital recording levels do not have headroom, so it is important to ensure that the levels are set correctly to avoid clipping or distortion.
The third type of recording level is input gain levels. Input gain levels are the levels at which the audio signal is amplified before it is recorded. Input gain levels are typically adjusted using a preamp or other input device. The goal of input gain is to maximize the signal-to-noise ratio (SNR) of the recording. SNR is the ratio of the signal level to the noise floor level. Higher input gain levels can result in a higher SNR, but they can also increase the risk of clipping or distortion.
Today, digital recording levels are the most popularly used recording levels in audio engineering. This is because digital recording levels offer greater precision and consistency than analog recording levels. Additionally, digital recording levels allow for greater flexibility in the mixing and mastering process, as the levels can be easily adjusted without the risk of introducing noise or distortion. However, it’s important to note that analog recording levels are still used in some professional recording studios, particularly for mastering and other critical stages of the recording process. Additionally, input gain levels are still important in both analog and digital recording setups, and they play a crucial role in ensuring the overall quality and clarity of the final product.
Why You Don’t Need to Stay at 0db FS these days
In the past, recording at 0dB Full Scale (FS) was common practice to ensure the highest possible quality. However, modern audio equipment is capable of handling higher levels without distortion, so it is no longer necessary to record at 0dB FS. With the advent of digital audio, it became possible to record audio at higher levels without introducing distortion. This is because digital audio has a higher dynamic range than analog audio, which means that it can handle a wider range of volume levels without distortion. Additionally, modern audio equipment, such as preamps and analog-to-digital converters (ADCs), are designed to handle higher levels without introducing distortion. Some equipment even has built-in limiters that prevent distortion from occurring at high levels. Finally, modern digital audio workstations (DAWs) have sophisticated metering and gain staging tools that make it easier to achieve optimal recording levels without clipping or distortion. Overall, the combination of improved hardware and software has made it possible to record at higher levels without sacrificing audio quality.
What is Headroom?
Headroom is the amount of space between the loudest part of a recording and 0dB FS. This is important because it allows for the recording to have some breathing room, and not be too close to the maximum level that can be recorded without distortion. By leaving some headroom, you can avoid clipping, which is when the audio signal exceeds the maximum level that can be recorded without distortion, and this can cause unwanted distortion and degradation in sound quality. It is therefore important to be mindful of headroom when recording audio, as it can greatly impact the final result and the overall listening experience for your audience.
What is gain-staging?
Gain-staging is a fundamental component of the recording process that involves optimizing the sound quality of each component in a recording chain. This process involves adjusting the gain on the microphone or instrument, setting the preamp to the optimal level, and fine-tuning the mixer. By taking the time to properly gain-stage your recording chain, you can ensure that every element of your sound is captured with clarity and depth. Proper gain-staging can also help prevent distortion and clipping, which can negatively impact the final mix. In short, gain-staging is a critical step in the recording process that should never be overlooked.
Why are things measured in Full Scale (or FS)?
Full Scale (FS) is the highest level at which an audio signal can be recorded or played back without distortion. It is an important reference point for measuring levels in digital audio, as it ensures that the audio signal is within the acceptable range for the equipment being used. In addition to FS, there are other important considerations when working with digital audio, such as bit depth and sampling rate.
Bit depth refers to the number of bits used to represent each sample of the audio signal, and determines the dynamic range and resolution of the signal. Sampling rate, on the other hand, refers to the number of samples taken per second, and affects the frequency response and accuracy of the signal. Together, these factors play a crucial role in producing high-quality digital audio recordings and reproductions.
Equipment calibration of pro-audio equipment vs consumer audio equipment
Pro-audio equipment is designed to deliver high-quality and consistent performance, making it essential for professional recording studios and live sound settings. Calibration is an important aspect of maintaining the accuracy and consistency of pro-audio equipment, and it is typically performed to much higher standards than consumer audio equipment.
Calibration involves adjusting and testing the equipment to ensure that it meets specified performance criteria. This can include measuring the frequency response, distortion, noise floor, and other parameters to ensure that they are within acceptable tolerances.
Pro-audio equipment is typically calibrated to a much tighter tolerance than consumer audio equipment, with tolerances as low as +/- 0.1dB. This level of precision ensures that the equipment delivers accurate and consistent performance, which is essential for professional recording and live sound applications.
In addition to tight tolerances, pro-audio equipment may also be calibrated to a higher sample rate and bit depth than consumer audio equipment. For example, while a consumer audio interface may only support 24-bit/96kHz recording, a pro-audio interface may support 32-bit/192kHz recording. This higher sample rate and bit depth can help to reduce noise and distortion and improve overall sound quality.
Overall, calibration is a critical aspect of maintaining the performance and accuracy of pro-audio equipment. By ensuring that the equipment is calibrated to the highest standard, professionals can be confident that they are delivering the highest quality audio possible.
