I voice record a lot and the recorder outputs in WAV. These recordings are usually > 1hr. I don't care very much about audio quality but want the files compressed for cloud storage backup.
Is there an easy/graceful way to do this on Windows? The guide I found for Media Player (first burn to a CD and then rip it as MP3) is kind of dumb! I don't want to do it online (some confidential info) and am not looking for shady freeware with ad popups.
Mac has "To MP3 Converter" which reviews said struggles with longer files and is also a monthly subscription, not good.
I can do this on Ubuntu with ffmpeg
with mixed results, especially with longer files.
soundconverter
... it supports a wide variety of formats (based on GStreamer), but i would suggest to simply use OPUS for best quality/size-ratio or FLAC for lossless compression.
