With this plugin, you can analyse the meta data of an audio file, detecting its encoding, sample rate, duration, and number of channels. It also provides a compatibility mode to directly parameterise Google Speech API.
It seems that it does’t work 100% of the time for mp3 files. Could I send some of the mp3 files that aren’t working? Maybe you could test them and see why its not working for them.
Also, is it possible at retrieve the files covert art and make it work for mp4 or m4a files?
Some files may either exceed the 30 backend seconds processing time OR their metadata may simply be wrongly formatted.
Unfortunately there isn’t much I could do here, besides rebuilding the plugin to an external infrastructure allowing additional processing - but then the plugin would become as a subscription - would you be keen on this solution?
