Frequently asked questions
Why convert FLAC to WAV?
FLAC doesn't play natively in the Apple ecosystem (iTunes/iPhone without an extra app) and is heavy on phones. ALAC keeps lossless within the Apple world; MP3/M4A cut the size by ~4× for everyday use. WAV is the WORKING format: lossless editing, accepted by every audio software, and what telephony/IVR systems usually require (8 kHz mono WAV).
Where do FLAC files come from?
Typically from lossless CD rips (EAC, dBpoweramp), hi-res music stores (Bandcamp, Qobuz) and live show archives and field recordings. Compression levels 0–8 only change encoding speed, never quality (the output is always identical to the original); the header stores an MD5 of the decoded audio for verification.
Is it worth using WAV?
WAV is the WORKING format: lossless editing, accepted by every audio software, and what telephony/IVR systems usually require (8 kHz mono WAV). Microsoft/IBM RIFF container (1991); 16-bit/44.1 kHz stereo is 10.1 MB/min; RIFF has a 4 GB ceiling — longer recordings use W64 or RF64.
Do I lose quality when converting FLAC to WAV?
No: FLAC and WAV are lossless formats. The decoded audio is bit-for-bit equivalent — what changes is the container and the compression method.
What if I need a transcript of this audio?
After converting, you can transcribe the file with AI on VoxScriber: 30 free minutes per month, with automatic punctuation and speaker identification. Ideal for WhatsApp audio messages, meetings, and interviews.
Is my file sent to any server?
No. All processing is local (FFmpeg compiled to WebAssembly running on the page). The file never leaves your device—it even works offline after the page loads.
Is there a size or quantity limit?
The limit is 300 MB per file (browser memory). There is no limit on the number of uses. For larger files, VoxScriber processes them on the server with uploads up to 5 GB.

Tools
Convert FLAC to MP3
MP3 is the format that opens on ANY device made since the 1990s — the safe choice for sharing, attaching to email, and playing on your car stereo.
Convert FLAC to M4A
AAC delivers the same quality as MP3 with about 30% less space — it's MP3's technical successor and the Apple ecosystem standard.
Convert FLAC to OGG
OGG compresses well with high quality and is an open, royalty-free format—great for web and games.
Convert MP3 to WAV
Leaving MP3 usually means needing WAV to edit without accumulating loss (recompressing MP3 degrades every generation) or a format required by a specific system — IVR/telephony wants 8 kHz WAV, iPhone ringtones want M4R.
Convert M4A to WAV
Older stereos, car radios, and some corporate systems won't open M4A — an iPhone voice memo arrives and no one can play it.
Convert M4B to WAV
M4B features (chapters, resume-where-you-left-off) only work in Apple apps and dedicated readers — many players won't even open the file.
