Frequently Asked Questions
What is a sample rate?
The sample rate is how many audio samples are stored per second, measured in hertz (Hz). 44,100 Hz (44.1 kHz) is the CD and music standard; 48,000 Hz (48 kHz) is the video and broadcast standard. A higher rate captures higher frequencies.
Does it change the pitch?
No. This is a true resampler — it recalculates the samples for the new rate, so the audio keeps the exact same pitch and the exact same duration. Only the sample rate changes.
44.1 kHz vs 48 kHz — which should I use?
Use 44.1 kHz for music, CD, and streaming audio. Use 48 kHz for video, film, and broadcast — it's the standard most video editors and platforms expect. Matching the surrounding project avoids resampling artifacts down the line.
Why is one rate button disabled?
The preset that matches your file's current sample rate is disabled — there's nothing to convert. The tool shows your source rate next to the file name, so you can see exactly what you're converting from.
Will downsampling lose quality?
Lowering the sample rate (e.g. 48 kHz → 8 kHz) discards the highest frequencies, which is expected and exactly what telephony or speech models want. Raising the rate (e.g. 44.1 → 48 kHz) won't add detail that wasn't there, but makes the file compatible with higher-rate workflows.
Is my audio file uploaded to a server?
No. The sample rate converter runs entirely in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded, stored, or analyzed.
What audio formats are supported?
MP3, WAV, M4A, FLAC, OGG, and AAC. Anything your browser can decode via the Web Audio API will load, up to 200 MB. You can export the result as MP3 or WAV.
