Sample Rate and Bit Depth for Exporting Your Audio

Sample rate and bit-depth for exporting

When exporting music from your Digital Audio Workstation (DAW), it's important to choose the right settings to ensure the highest audio quality possible. Two key settings to consider are the sample rate and bit depth. In this blog, we'll discuss what sample rates and bit depths are, how they affect your music's sound quality, and the best settings to use when exporting your music for different formats.

Sample Rate

The sample rate refers to the number of samples of audio taken per second. The standard sample rate for most music is 44.1 kHz or 48 kHz. The higher the sample rate, the more detail is captured in the audio. This means that higher sample rates can capture more accurate representations of high-frequency content and transients, resulting in better sound quality.

 

Bit Depth

Bit depth refers to the number of bits used to represent each sample of audio. The standard bit depth for most music is 16-bit or 24-bit. A higher bit depth allows for a greater dynamic range and more accurate representation of the audio waveform. This results in more detail and clarity in the sound.

 

Choosing the Right Sample Rate and Bit Depth for Exporting Music

When exporting your music, it's important to choose the right sample rate and bit depth to ensure the best audio quality. However, it's also important to consider the intended format of your music.

For example, if you're exporting your music for CD, the recommended sample rate is 44.1 kHz and the recommended bit depth is 16-bit. This is because CDs can only play at 44.1 kHz, and 16-bit is the standard bit depth for CDs.

If you're exporting your music for online streaming services like Apple Music or Spotify, the recommended sample rate is 44.1 kHz or 48 kHz, and the recommended bit depth is 24-bit. While both services accept music with a sample rate of 44.1 kHz, Spotify's preferred sample rate is 48 kHz. Additionally, a higher bit depth ensures the best possible sound quality for the streaming services' high-quality audio options.

For high-resolution audio formats like FLAC or WAV, a sample rate of 96 kHz or higher and a bit depth of 24-bit or higher is recommended. This allows for the highest possible audio quality and detail.

 

Dithering

When exporting music from your DAW, it's also important to consider dithering. Dithering is a process that adds a low-level noise to the audio to reduce the distortion caused by bit depth reduction during export. It's important to apply dithering when exporting audio at a lower bit depth than the original recording. For example, if you recorded your music at 24-bit and are exporting at 16-bit, dithering should be applied to ensure the best possible sound quality.

Conclusion

Choosing the right sample rate and bit depth when exporting your music is essential to ensure the highest quality. It's important to consider the intended format of your music. Different formats have different recommended settings. Additionally, dithering should be applied when exporting audio at a lower bit depth than the original recording. By following these guidelines, you can ensure that your music sounds its best across all platforms and formats.
