let iter_len = (waveform.len() - n_samples_per_tensor) / shift + 1;

Here waveform.len() could be less than n_samples_per_tensor, which results in iter_len to be extremely large:

[src/transcribe.rs:97] n_samples_per_tensor = 238559
[src/transcribe.rs:97] waveform.len() = 168511
[src/transcribe.rs:97] waveform.len() - n_samples_per_tensor = 18446744073709481568

Replacing subtraction with saturating_sub fixes the issue.

Nice catch! I just pushed your correction.
