The short answer: Sample rate determines how many snapshots of audio are captured per second (44,100 or 48,000 for most music). Bit depth determines the precision of each snapshot (16-bit for final delivery, 24-bit for recording and mixing). For most producers: record at 24-bit / 44.1 kHz, mix at the same settings, and export your final master at 16-bit / 44.1 kHz WAV for streaming.
Genesis Mix Lab is an AI-powered mixing and mastering platform that accepts audio at any standard sample rate and bit depth. Understanding these settings helps you deliver the best possible source material for mixing and mastering, whether you use our platform or work with a human engineer. For a more detailed technical reference, see our comprehensive sample rate and bit depth guide.
What Is Sample Rate?
Sound is a continuous wave of air pressure changes. Digital audio captures this wave by taking measurements (samples) at regular intervals. Sample rate is how many of these measurements happen per second, measured in Hertz (Hz) or kilohertz (kHz).
At 44.1 kHz, your recording device captures 44,100 snapshots of the audio waveform every second. At 48 kHz, it captures 48,000. At 96 kHz, it captures 96,000. More snapshots per second means higher frequency resolution and the ability to capture higher-pitched sounds accurately.
Here is the critical concept: a sample rate can accurately capture frequencies up to half its value (this is called the Nyquist frequency). So 44.1 kHz captures frequencies up to 22,050 Hz, and 48 kHz captures up to 24,000 Hz. Since human hearing tops out around 20,000 Hz (and degrades with age), both 44.1 kHz and 48 kHz capture the full range of audible sound.
Common Sample Rates and When to Use Them
| Sample Rate | Max Frequency | Use Case |
|---|---|---|
| 44.1 kHz | 22.05 kHz | CD standard, streaming music, most music production |
| 48 kHz | 24 kHz | Video production standard, music for film/TV/YouTube |
| 96 kHz | 48 kHz | High-resolution audio, archival recording |
| 192 kHz | 96 kHz | Ultra-high-resolution, specialized scientific use |
For most music producers, 44.1 kHz is the right choice. It is the standard for all streaming platforms, avoids unnecessary file size increases, and captures the full audible frequency range. Use 48 kHz if your music will be used in video. Higher sample rates offer diminishing returns for the vast majority of music production workflows.
What Is Bit Depth?
While sample rate determines how often audio is measured, bit depth determines the precision of each measurement. Think of it as the resolution of each snapshot. More bits means more possible values for each sample, which translates directly to a wider dynamic range (the difference between the quietest and loudest sounds the format can represent).
16-bit audio has 65,536 possible values per sample and provides a dynamic range of approximately 96 dB. This is the CD standard and the delivery format for most streaming platforms. It is more than sufficient for finished, mastered audio.
24-bit audio has 16,777,216 possible values per sample and provides a dynamic range of approximately 144 dB. This extra headroom is invaluable during recording and mixing because it means you can record at conservative levels (leaving plenty of headroom) without the quiet parts disappearing into the noise floor.
32-bit float audio is used internally by most modern DAWs for processing. It provides essentially unlimited headroom within the DAW, which is why your internal mix bus can exceed 0 dBFS without clipping. You rarely need to think about 32-bit float; your DAW handles it automatically.
Practical Recommendations for Producers
- Recording: Always record at 24-bit. The extra dynamic range gives you headroom to record at safe levels (-18 to -12 dBFS peaks) without worrying about noise floor. There is zero downside to recording at 24-bit in 2026.
- Mixing: Work at whatever sample rate you recorded in. Do not change the sample rate mid-project. Your DAW processes internally at 32-bit float or 64-bit float, so bit depth during mixing is handled automatically.
- Exporting stems for mixing: Export stems at 24-bit WAV at your session's native sample rate. Do not dither stems. Dithering is only for the final delivery format conversion. Learn how to export stems properly for the best results.
- Final master delivery: Export your finished master at 16-bit / 44.1 kHz WAV with dithering applied (POW-r or MBIT+ algorithms are excellent choices). Some distributors accept 24-bit, which is preferred if available.
- For AI mastering: Upload the highest quality file you have. Our AI mastering engine accepts all standard formats and optimizes the output for your chosen delivery platform.
Common Misconceptions
- "Higher sample rate always sounds better." Not true. 44.1 kHz captures the full audible frequency range. Higher sample rates increase file sizes and CPU load with minimal or no audible benefit for finished music.
- "I should always use the highest settings possible." Recording at 192 kHz / 32-bit creates enormous files, taxes your CPU, fills your hard drive faster, and provides no meaningful quality improvement for music that will be delivered at 16-bit / 44.1 kHz.
- "16-bit is low quality." 16-bit provides 96 dB of dynamic range, which is more than enough for finished, mastered audio. The entire dynamic range of a professionally mastered track fits comfortably within 16-bit. The limitation matters during recording (where you need extra headroom), not during delivery.
- "Sample rate conversion is harmless." Converting between sample rates (for example, recording at 48 kHz and delivering at 44.1 kHz) introduces subtle artifacts. It is best to record at your intended delivery sample rate when possible. If conversion is necessary, use a high-quality sample rate converter.
