invalid sample: TooWide when running audio transcription example

[SimunKaracic]

I'm trying to run the audio transcription example:

cargo run --example audio_transcription

using a file I recorded using sox sox -d audio.wav and then converted with this command: sox audio.wav -r 16000 -c 1 audio16k1.wav.

I get the same error, with either of the audio files:

thread 'main' panicked at 'invalid sample: TooWide', examples/audio_transcription.rs:51:24

Any ides on what I'm doing wrong?

Full output:

Seems like an issue with hound, as that doesn't touch whisper_rs code yet. It seems that you may have written a floating point audio file? It would be attempting to read 32 bits for a f32 sample vs the 16 required for i16 samples, resulting in a TooWide error.

Gonna go ahead and close this, feel free to reopen if you still have issues.
