What format .wav does the whisper model take in?

Next question :^)

When I record audio with unreal engine, the API doesn't accept it.

Is there a specific format of .wav that the API must have to work?

[DominicHughes899]

Specifically, audio prerecorded by windows sound recorder runs happily inside my unreal c-api implementation.

However, when recording input through unreal. The output is a .wav, but the format is wave_format_pcm. The accepted format seems to be wave_format_ex. Is this explicitly required, could I change the src to accept it?

Or if not, does anyone know of a way to convert pcm to ex in this case?

The accept waveform api takes two argument, the actual sample rate of your data and your data in a float array. Each element in the array is in the range -1 to 1.

only a single channel is supported.

hope it helps.
