I use the Audio Recorder Plugin to record user voice input. As a next step I want to use a speech-to-text service (Google) to get the transcript of the user input.
The Audio Recorder Plugin saves the file in stereo quality, but Google only accepts mono.
Any ideas on how to switch to mono? Is there any option inside of the Audio Recorder Plugin? Or does someone know any webservice I could use to convert my audio file? Haven’t found a good solution yet.
