Preferred Ogg quality setting

(1/4) > >>

ElFishie:
I wonder what your choices are for encoding ogg-files for use in rockbox.

Browsing other sites I found rare opinions suggesting less than q2 and a few over q7 mostly suggesting q10 right away. In between arguments spin around transparency (in portables), disk space and battery life.

My stuff is mostly q5, but this is not the result of any in-depth analysis. Rather a little non-ABX testing.

So what is your take?

edit:
would be nice to learn about the reasons that drove your choice:
- audio quality (maybe rockbox specific: high quality ogg had been reported to skip)
- file size
- battery life (maybe rockbox induced parsimony with battery life: earlier X5 builds had been too generous)
- insanity
- etc.

Febs:
As we discussed via PM, please edit your post to indicate specifically what you are asking with respect to Ogg and Rockbox.  Thanks!

For any votes in the q8+ group, you can just go ahead and assume there's "insanity" involved. ;)

I personally use Q4.25 on aoTuV's Release 1 encoder.

Siku:
I use q2 on aoTuv's latest encoder. I know it's not transparent on every sample but in real life use, I can't tell the difference with the original audio. I even tried to ABX between q2 and original, but I failed. The main reason to use such a low bitrate is the file size.

Using anything above ~128kbps on DAP is an overkill. Most of the people couldn't tell the difference on 128kbps Vorbis even with very hi-quality HiFi system. But by all means, use what quality you ever want. It's just highly recommended to do some blind testing to see what quality is transparent for you.
