Do you ever find yourself lost in the world of audio production, not sure which knob to turn or which button to press? You’re not alone. The world of audio can be overwhelming, especially when it comes to technical terms like buffer size. But fear not! In this blog post, we’re going to break down everything you need to know about buffer size in audio production.
Whether you’re a musician, podcaster, or video producer, getting the most out of your audio is key. So, let’s get into it and see how you can use buffer size to take your audio production to the next level.
What is buffer size? Buffer size refers to the amount of audio data that is processed at one time. It affects audio quality and latency, with a smaller buffer size providing lower latency but potentially lower audio quality, while a larger buffer size offers higher quality but higher latency.
What buffer size should you use?
Buffer size refers to the amount of audio data that a digital audio workstation (DAW) processes at a time. The larger the buffer size, the more processing power and memory the DAW requires to run smoothly. Conversely, a smaller buffer size reduces the processing power and memory required by the DAW, but it can lead to latency and other audio interruptions.
The most common buffer sizes found in DAWs are 32, 64, 128, 256, 512, and 1024. When mixing, it is recommended to adjust the buffer size to 512 or 1024 to ensure smooth processing of audio plugins. When recording, it is best to use a slightly higher buffer size to avoid crackling and other audio interruptions. In this case, a buffer size of 128 to 256 is recommended.

What is the best buffer size for recording?
When it comes to recording, it is important to choose an appropriate buffer size to ensure a smooth and seamless recording process. Most experts recommend a buffer size of 128 to 256 for recording to avoid latency and ensure smooth audio processing. This is because larger buffer sizes tend to increase latency and may result in delays in the recording process.
…it is important to note that the appropriate buffer size for recording may vary depending on the specific task at hand.
Additionally, using a smaller buffer size can cause effects on tracks such as reverb or pitch correction to struggle to run in real-time. However, it is important to note that the appropriate buffer size for recording may vary depending on the specific task at hand.
For example, a smaller buffer size may be suitable for certain applications that require a faster response time, while a larger buffer size may be necessary for more complex projects that require more processing power and memory.
What is the best buffer size for mixing and mastering?
When mixing, it is recommended to adjust the buffer size to 512 or 1024 to ensure smooth processing of audio plugins. This is because mixing involves running many plugins simultaneously, which can require more processing power and memory. Using a larger buffer size can help to ensure smooth processing and prevent audio interruptions.
When it comes to mastering, the appropriate buffer size may vary depending on the specific task at hand. However, in general, it is recommended to use a buffer size of 512 or 1024 for mastering to ensure smooth processing of the final mix and avoid any audio interruptions.
It is important to note that the appropriate buffer size may also depend on other factors, such as the specific DAW being used, the processing power of the computer, and the sample rate being used. Therefore, it may be helpful to experiment with different buffer sizes to find the one that works best for the specific task at hand.
How does buffer size affect latency?
Buffer size and latency are closely related concepts in digital audio processing. Buffer size refers to the amount of audio data that a digital audio workstation (DAW) processes at a time, while latency refers to the delay between when a sound is generated and when it is heard.
The table provides an overview of different buffer sizes commonly used in audio production and their impact on audio performance in terms of latency. Choosing the appropriate buffer size is crucial to strike a balance between low latency and system resource requirements.
| Buffer Size | Latency (ms) | Impact on Audio Performance |
|---|---|---|
| 32 Samples | 0.73 | Minimal latency, suitable for real-time applications such as live performances or recording with software instruments. |
| 64 Samples | 1.46 | Low latency, recommended for most audio production tasks where real-time monitoring is required. |
| 128 Samples | 2.92 | Moderate latency, suitable for general audio editing and mixing tasks. |
| 256 Samples | 5.83 | Higher latency, appropriate for projects with a large number of tracks and effects processing. |
| 512 Samples | 11.67 | Significant latency, better suited for projects with heavy CPU usage or older hardware. |
| 1024 Samples | 23.33 | High latency, useful when working with resource-intensive projects or older systems. |
The buffer size affects latency in that a smaller buffer size reduces the delay between when a sound is generated and when it is heard, but it can also cause audio interruptions and glitches. A larger buffer size, on the other hand, increases the delay but ensures smoother audio processing and fewer interruptions.
In addition, sample rate also affects buffer size and latency. The higher the sample rate, the more samples are processed per second, which reduces the overall latency. For example, a higher sample rate may require a larger buffer size to process the same amount of audio data and maintain low latency.
When should you change the buffer size?
When to change the buffer size depends on the task you are performing on your computer. For recording, it is recommended to use a lower buffer size to avoid latency, which is the delay between the input you give your computer and the output you hear from your speakers or headphones.
It is also important to consider your computer’s processing power and available memory when choosing a buffer size. If you are experiencing audio dropouts or glitches, you may need to increase your buffer size to give your computer more time to process audio data.

Key takeaways
This article covered buffer size. Here are some key takeaways:
- Buffer size in audio refers to the amount of audio data that is processed at one time.
- Choosing the right buffer size is crucial to achieving the best possible sound quality in your audio production.
- Buffer size and latency are inversely related, with lower buffer sizes resulting in lower latency and larger buffer sizes potentially resulting in higher latency.
