[Vorbis] MP3/Vorbis/Opus: What I think I hear

[Sergei Steshenko]

"Unfortunately my search for a good free player for Android was not very successful" - I presume you are using an Android device.
If that's the case, portable devices have really bad electronics from the point of view of HiFi - because of low voltage and output amplitude being close to power rails.
My point is that you are not really comparing one lossy format to another, but rather how the lossy formats artifact sound on bad electronics.
"you can't just install codes" - players for all the formats you mention exist as command line applications, and there are interactive shells for Android.

Hi!

Sorry, I know the rules for comparing objective subjective listening impressions, but I'd like to know whether from the algorithmic or implementer's point of view the following personal impressions can be confirmed:

Comparing MP3 with Vorbis at rather high bitrates, I had the impression the Vorbis sounded more crispy, while MP3 sounded somewhat softened.  I preferred Vorbis for that reason.
When comparing Opus to Vorbis, I got the impression that Opus has a slight tendency towards MP3, but noe I feel Vorbis' crispyness is maybe a little too much, and I think I'll prefer Opus. Unfortunately my search for a good free player for Android was not very successful (the shipped players all can't play Opus, and I think you can't just install codes, or can you?)

Regards,
Ulrich
