JRemote (iOS) transcode audio(?)
« on: July 17, 2021, 12:16:56 pm »

I was able to find a few posts on the subject, but just for clarification…

If I choose a high definition audio file (e.g., 24bit/96kHz) to play via JRemote on my iPhone, and ‘transcode audio’ is disabled, does that mean JRemote is decoding the 24bit audio? That is, some people would imply it’s not possible for an iPhone to actually do an accurate job of the heavy lifting. That said, relative to MP3 data, I can see the data transfer rate slow to an almost crawl which would imply to me the original data is being transferred and locally decoded(?)

Of note, I am using a portable, but high quality headphone amp between iPhone and studio headcans. The amp is capable of bluetooth or MFi cable connections. Should I hear a difference?

TIA :)

I’m only looking for verification. Is JRemote capable of bitperfect playing of 24bit flacs, or not?

good question.

I believe Apple quietly added FLAC support to iOS/iPadOS as of v11 (so it's been in there for sometime now).

I will say that when I stream FLAC to my iOS device in JRemote, it sounds noticeably better than having it transcoded to mp3; and other family members have confirmed.  unfortunately I have a substantial number of multi-channel recordings, which are a mess if you stream them to JRemote without transcoding to mp3.  Without transcoding, channels are "lost".  So then I went back and ripped the hi-resolution stereo mixes as well and use those when playing to an iOS device - which is fine since it's ultimately destined for headphone listening or car audio.
