About FLAC files
FLAC is lossless compressed audio. It is about half the size of WAV but keeps every sample. Many download stores and CD rips use it.
People convert FLAC to WAV because some editors, DJ players, CD burning tools and hardware samplers only accept WAV. The audio stays bit-for-bit the same.
How we convert FLAC to WAV
- Output
- 16-bit PCM WAV.
- Sample rate
- Kept from the FLAC unless you choose 44.1 kHz, 48 kHz or 96 kHz.
- Channels
- Stereo stays stereo unless you switch to mono.
Common problems and fixes
The source is a 24-bit FLAC.
Our WAV output is 16-bit, the audio CD standard. That is fine for playback and burning. Keep the FLAC if you need 24-bit for mastering.
A CD burning tool rejects the WAV.
Audio CDs need 44.1 kHz stereo. Set the sample rate to 44.1 kHz and convert again.
The WAV takes much more disk space.
That is expected. WAV has no compression, so it is about twice the size of the FLAC.
About FLAC to WAV Conversion
FLAC (Free Lossless Audio Codec) stores CD-quality audio in a compressed format that reduces file sizes by 50-70% without sacrificing a single bit of audio data. However, many professional audio workstations, hardware samplers, broadcasting systems, and legacy media players cannot open FLAC files directly. Converting FLAC to WAV decompresses the audio back to its original uncompressed PCM form, producing uncompressed 16-bit PCM audio.
Our FLAC to WAV converter uses our media engine to decode the FLAC bitstream and write standard RIFF WAV output. Our WAV output is 16-bit PCM. For a 16-bit FLAC, such as a CD rip, the WAV contains exactly the same sample values as the original recording. A 24-bit FLAC is reduced to 16-bit in the WAV. The sample rate stays as in the source unless you pick another one. The process typically completes in seconds, even for full album-length files.
Why Convert FLAC to WAV?
Professional audio editing tools demand uncompressed audio. Digital Audio Workstations like Pro Tools, Logic Pro, Ableton Live, and FL Studio import WAV files natively, but FLAC support varies — Pro Tools lacks native FLAC import entirely, and many hardware recorders and samplers only recognize WAV. Converting to WAV before importing ensures zero compatibility issues and eliminates the overhead of real-time FLAC decoding during editing sessions where every millisecond of latency matters.
Broadcasting and mastering workflows require WAV. Radio stations, podcast distribution platforms, and mastering engineers work exclusively with uncompressed audio to avoid any potential artifacts from decode-encode cycles. WAV files meet the technical requirements of broadcast standards like EBU R128 and ITU-R BS.1770 without requiring additional processing. When submitting masters for CD replication, vinyl cutting, or streaming distribution, WAV is the universally accepted delivery format.
