Convert FLAC to WAV
Drop a FLAC and download a 16-bit PCM WAV holding the same audio. Sample rate and channel count are preserved.
Nothing is lost in either direction between these two formats, so this conversion is purely about which file a downstream tool will open.
24-bit sources
The export writes 16-bit PCM. A 24-bit FLAC therefore loses its bottom 8 bits of resolution, which is inaudible on playback but does matter if the file is heading back into a mix for further gain staging and processing.
For archival work, keep the FLAC and decode to WAV only when a tool demands it.
Size
Expect about 10 MB per minute of 44.1 kHz stereo audio, so a full album runs several hundred megabytes. Exports stream to browser disk storage when it is available; without it, oversized jobs are refused rather than allowed to exhaust memory.
