Frequently asked questions
- Why is the output WAV instead of MP3?
- Browsers can decode many audio formats but only natively encode WAV. WAV is uncompressed, so the file is bigger; for a smaller MP3, run the joined WAV through our Audio Converter.
- Will the clips be re-encoded?
- Yes — we resample to a common sample rate (44.1 kHz) and bit depth (16-bit PCM) so the join is gapless. Audible quality is preserved; the only loss is from MP3 → WAV → MP3 round-trips, which is minimal.
- Can I add a crossfade between clips?
- Not yet — clips are joined edge-to-edge. For crossfades, use a desktop tool like Audacity or our Audio Cutter to overlap manually.
- Are my files uploaded?
- No — Web Audio decoding and rendering both happen in your browser.
- How long can the output be?
- Limited by your device's memory. A few hours of audio works on most laptops; multi-day recordings won't fit.
