I read through this article: https://habr.com/en/post/456182/ and was quite intrigued.

I...Hi Archimageo, InTheBoilerRoom and everyone else<br />I have been researching the subject of how Bluetooth transmits compressed (aac) files as well recently. Like InTheBoilerRoom I have found only anecdotal evidence, no systematic research. It is unclear whether compresses (aac) files are first decoded and then reencoded using aac, sbc or aptx. The information I did find suggest that the4 files jacobaccihttps://www.blogger.com/profile/12580479634083669984noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-20167429675520438192017-12-21T06:18:18.724-08:002017-12-21T06:18:18.724-08:00One of the details about Bluetooth that I'm un...One of the details about Bluetooth that I'm unclear about is how it handles transmission of multiple types of audio simultaneously, especially when having to mix multimedia audio with device sounds (ringer, notifications, etc.). I had a back-and-forth convo on the comments thread of an Ars Technica article several weeks ago regarding this.

Hi Arc...Multi Tone for Testing Lossy Audio Codecs<br /><br />Hi Archi. As I have participated at a Working Group on Audio Codecs (some years ago), I would suggest to use Multi Tone for testing. You will be “surprised” that the characteristic of the “lossy codec output” does change with different signals in both channels and with different phase of the signal in both channels. Also one has to “learn” to JR_Audiohttps://www.blogger.com/profile/00547557948411188806noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-31562434762487312912017-12-19T08:06:41.495-08:002017-12-19T08:06:41.495-08:00Cool man, thanks...
