Please test the following: $ ffmpeg -i inter.dts -ac 2 out16.wav $ ffmpeg -i inter.dts -ac 2 -acodec pcm_s32le out32.wav $ ffmpeg -i inter.dts -ac 2 -ab 640k out.ac3 $ ffmpeg -i inter.dts -ac 2 -ab 320k out.mp2 Iiuc, out32.wav sounds ok. Do the other three files sound ok for you or not? > Until I have a solution I've already edited my > services to perform this intermediary wave step > work-around on all conversions. You can do the intermediate step within FFmpeg, just play with -af aformat=s32.
