Fix mono WAV playing only the left speaker#14
Merged
Conversation
tuneR::writeWave defaults to extensible = TRUE, which writes WAVE_FORMAT_EXTENSIBLE and stamps a mono file with channel mask SPEAKER_FRONT_LEFT - so players route it to the left speaker only. write_audio now passes extensible = FALSE to write plain WAVE_FORMAT_PCM mono (channel_layout unknown), which plays on both speakers and transcodes to a clean mono mp3 (verified with ffprobe).
