Mono wav file reading broken?

[francisdb]

mrhector — 08/25/2024 9:36 PM I took a table and converted any stereo wav table sounds to mono since vpx standalone is unable to handle stereo wav files on linux when using 7.1 . I tried to reassemble the table but get an error:

Might be better to switch to https://docs.rs/hound/latest/hound/ instead of reinventing the wheel.

From our conversation on Discord. I run the following command in a powershell script to convert a stereo wav file to mono

ffmpeg -i inputfile.wav -ac 1 outputfile.wav

Attached are a couple examples of the wav files. I'll include the originals and the ones I've converted. This particular table, most of the existing wav files are already mono and I'm able to extract / reassemble the table if I don't make any changes. wav_examples.zip

Thanks, should be fixed in https://github.com/francisdb/vpxtool/releases/tag/v0.13.10

[mrhector]

Thanks! Noticed there are no binaries for that release. I think the release step was skipped for some reason in the github action.

@mrhector was because the release was marked as draft, they are available now
