Frequently Asked Questions
- What sample rate do I need?
- For video and broadcast: 48 kHz. For music: 44.1 kHz. Higher rates (96 kHz+) are only useful if you plan to edit heavily or pitch-shift.
- Does bit depth matter for MP3?
- No — bit depth only applies to WAV and FLAC. For MP3, the bitrate matters instead.
- Will converting up improve quality?
- No. Converting 44.1 to 96 kHz does not add information. It only standardises your library.
Sample Rate and Bit Depth Explained
Every digital audio file has two core properties: sample rate (how many times per second the waveform is measured) and bit depth (how much precision each measurement has).
Common Sample Rates
- 44 100 Hz — CD audio. The standard for music.
- 48 000 Hz — Video, television, and broadcast. The standard for anything on screen.
- 88 200 / 96 000 Hz — High-resolution music delivery.
- 176 400 / 192 000 Hz — Studio masters and archival.
Bit Depth
- 16-bit — 96 dB of dynamic range. Plenty for delivery.
- 24-bit — 144 dB of headroom. Studio recording standard.
- 32-bit — 192+ dB. Overkill for delivery, useful for heavy processing.
When to Convert
- Deliver a podcast to a platform that requires 48 kHz.
- Prepare music for CD duplication (44.1 kHz / 16-bit).
- Standardise a library of mixed files.
Note: Upsampling does not add information. Converting 44.1 to 96 kHz does not make audio sound better — it just changes the container.
