Should audio transcoding perhaps default to >192K?

[patters]

I recently bought gaming headphones which have a Dolby Headphone processor which takes a 5.1ch AC-3 feed. Transcoding 5.1 channels at 192K sounds pretty bad. I had been using my TV's speakers until now so it hadn't bothered me. I have tested that even my Synology NAS can transcode it at 640K in realtime. I know a few people have objected to the current Sony BDP profile transcoding DTS audio in mkv mainly because they can hear it sounds a lot worse.

Are there any reasons it shouldn't default to 640K, at least for 5.1 transcoded streams? Or is the problem that some renderers don't accept it?

640k seem a little excessive to me 320K would be a better level in my opinion and then even sloer servers and network would cope fine.

A Synology NAS is a slow server though. I think AC-3 encoding is pretty quick. 192K is fine for 2ch but sounds decidedly bad with 5.1, and lots of people are feeding the output into a surround receiver. I mean obviously we are free to mod the profiles.xml, but I'm wondering if the bar is set a bit too low. Like you say, maybe 320 or 384 should be the default.

yer sorry i ment 384k lol

I'm a bit worried this might possibly break some profiles so would rather not play with it

If you want to change the default, you can unzip serviio.jar, find serviio.properties and change value of property

transcoding_default_audio_bitrate

Nice. I wonder if we should collect all these parameters for the documentation or the FAQ.

id build a wiki site for the project but have no were to host it atm.

I'm planning to put up a page in the Support page listing all -D parameters at least.... the unzipping jar stuff is a bit hardcore

thats why you keep us around cause we are the hardcores
