About BWF
The European Broadcasting Union defined Broadcast Wave in 1997 so radio and TV could pass recordings between systems with their facts kept. Zoom, Sound Devices and Tascam recorders and every audio editor write it.
A BWF is a WAV with a bext chunk: a description, who made it, when, and a time reference that lines the sound up with picture. Most are saved with the .wav extension, some with .bwf.
Filepeek plays it with its whole waveform, at 16, 24 or 32 bit, mono, stereo or many channels, and Export saves an MP3 or a WAV.

Questions
How do I play a .bwf file?
Drop it on this page or press Peek a BWF. It plays at once with its whole waveform.
Is a BWF the same as a WAV?
Yes, with a chunk of broadcast facts added. Any program that plays WAV plays it, and renaming it to .wav changes nothing inside.
Can I make it smaller to send?
Yes. Choose Export, then Save as MP3.
Is my recording uploaded?
No. The recording opens inside your browser and never leaves your device.
