There are a few commercial graphical apps for the Mac and you can even use Garageband, but I always wanted to be able to convert MIDI files using the command line since it’s easier and I can automate the whole process. On the Mac we can use Timidity++ or Fluidsynth, both available using homebrew. Fluidsynth Support for ripping Audio CDs as well as transcoding all supported audio formats using the Converter component. Full ReplayGain support. Customizable keyboard shortcuts. Open component architecture allowing third-party developers to extend functionality of the player. Here is an example of how to find all .wav files larger than 50M, convert them to mp3 and then delete the original wav file (aka, batch mode -- alter the find command to create your 'batch') find . -size +50M -iname *.wav -type f -exec ffmpeg -i {} -codec:a libmp3lame -qscale:a 2 {}.mp3 -y \; -exec /bin/rm {} \; m3u8 hls stream to wav in one step with ffmpeg. I'm using to ffmpeg to extract 10" snippets in WAV audio from a m3u8 hls stream in two steps like this: ffmpeg -i XXXX.m3u8 -t 10 -c copy -bsf:a aac_adtstoasc -vn output.acc ffmpeg -i output.acc output.wav. How can I do it in just one step to avoid the intermediate file and maybe speed the process? Audio File (s) Download Now. 1. Download Switch Audio Converter. Download Switch Audio Converter.

Then use this oneliner from within your main folder: for /r %%f in (*.ogg) do ogg_to_mp3 "%%f" "%%~dpnf.mp3". To explain the magic %%~dpnf: This is used to extract parts from %%f (the full filename of the ogg file), where d is the Mac lets you convert text to speech using command line utility “say”. It also lets to generate an audio file in various formats and voices. This is pretty handy to generate audio file given the text.
