generates wavs with a 46-byte I think Sox stat fails

Probably text, not sound

Sox stat output but will open in audacity so presume its the header?

What file were you decoding, what were the exact commands that you used, and what was the command output?

This worked for me:

$ opusdec zero/common_voice_en_12168.opus out.wav
Decoding to 48000 Hz (1 channel)
Encoded with libopus 1.3
ENCODER=opusenc from opus-tools 0.1.10
ENCODER_OPTIONS=--quiet
Decoding complete.        
$ sox out.wav -n stat
Samples read:             48000
Length (seconds):      1.000000
Scaled by:         2147483647.0
Maximum amplitude:     0.314453
Minimum amplitude:    -0.168823
Midline amplitude:     0.072815
Mean    norm:          0.029068
Mean    amplitude:     0.000198
RMS     amplitude:     0.053175
Maximum delta:         0.049927

Rough   frequency:          636
Volume adjustment:        3.180
$ 

This decodes the 8611 byte opus file to a valid 96044 byte wav file.

opusdec --rate 16000 I will have to go through and capture the files but its quite a few but I am decoding several gb. leave me to it and will post I just did a quick script to delete the dross and pull more than needed then trim qty. I will get back to you with better details as yeah single files and many of them work perfectly but not all, which has confused the hell out of me :) There always seems just a few in in folder of the Mlcommons dataset or its opusdec but switched to Debian as something also a but strange with the filemanager of ubuntu as really doesn't like lots of files.

From the current en language sub section of mlcommons here are the ones from hey/ Suspicious silence: 0 hey/common_voice_en_21973802.wav Suspicious silence: 0 hey/common_voice_en_22028904.wav Suspicious silence: 0 hey/common_voice_en_1298494.wav Suspicious silence: 0 hey/common_voice_en_27602.wav Suspicious silence: 0 hey/common_voice_en_22157064.wav Suspicious silence: 0 hey/common_voice_en_17885387.wav Suspicious silence: 0 hey/common_voice_en_17762242.wav Suspicious silence: 0 hey/common_voice_en_17873527.wav Suspicious silence: 0 hey/common_voice_en_17906428.wav Suspicious silence: 0 hey/common_voice_en_22118045.wav

If I test singular files always seems to work but bulk decoding its either mlcommons or opusdec. I will close as no one shouted hey yeah happens to me :)
