Frequently Asked Questions
Use a mono or stereo PCM/float WAV or MP3 file that your browser can decode. AAC/M4A, Ogg, FLAC and other containers are not supported. Output is always an uncompressed 16-bit PCM WAV file.
No. Metadata reading, decoding, trimming, resampling and WAV encoding run on this device. No audio is played automatically. Cancel discards the pending output; browser-native decoding or resampling may take a moment to finish releasing resources.
Choose mono or stereo audio up to 30 MB and 2 minutes. WAV output is capped at 64 MB. Lower the sample rate, choose mono or shorten the trim for long recordings. Native decoding can temporarily use about 46 MB of memory for a 2-minute stereo recording, plus working buffers; use short clips on small devices. Processing stops after 3 minutes. WAV usually uses more storage than compressed input, and metadata and cover art are not preserved.
