Frequently asked questions
- Can I merge audio files in different formats?
- Yes. SnapOtter normalizes sample rates and channels automatically, so you can combine MP3, WAV, FLAC, and other formats into one output file. Everything runs on your local server.
- Is there a limit to how many files I can merge?
- There is no hard limit. You can combine as many files as needed since processing runs on your own server and is not constrained by cloud upload caps.
- Will the merged file have gaps between tracks?
- No. Files are joined seamlessly end to end. If you want pauses between segments, add silent clips at the desired positions. All processing stays on your network.
