What lossy format to use for Bluetooth transfer? 2018-06-12 13:08:15 I am considering getting a bluetooth speaker, mainly for use in my garden, using audio source from my phone. It seems to be quite hard getting some information in advance what bluetooth codecs are supported by which device, the most i can find is bluetooth version number and A2DP version number, but no info on codecs. Now, I want to avoid transcoding audio during bluetooth playback at *ALL* costs. Currently my audio format on my phone is 96 kbps Opus, which is perfectly fine, but i know this won't play over bluetooth without transcoding. What coded should I go for to have 100% guarantee that it's being played back by the bluetooth speaker natively without transcoding at acceptable sound quality? Will I have more luck with LAME -V5 or should i stick to AAC? What parameters should I look for for the speaker to avoid transcoding?
