Frequently Asked Questions

What audio formats are supported?
Any format your browser can decode: MP3, WAV, OGG, AAC, FLAC, M4A, WebM audio, and more. The list varies by browser — Chrome has the widest support.
Does normalization affect quality?
Peak normalization scales the audio so the loudest peak reaches -0.1 dBFS. It does not change pitch or add distortion — it simply makes the clip louder or quieter proportionally.
Why WAV output?
WAV is lossless and universally compatible. Since browsers cannot encode MP3 natively without extra libraries, WAV is the most reliable, highest-quality option for download.
Is there a file size limit?
No server-side limit. Browser memory limits apply — most modern devices handle files up to 500 MB or several hours of audio without issues.
