"Unfortunately my search for a good free player for Android was not very su=
ccessful" - I presume you are using an Android device.
If that's the case, portable devices have really bad electronics from the p=
oint of view of HiFi - because of low voltage and output amplitude being cl=
ose 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 ex=
ist as command line applications, and there are interactive shells for Andr=
oid.

Hi!

Sorry, I know the rules for comparing objective subjective listening impres=
sions, but I'd like to know whether from the algorithmic or implementer's p=
oint 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.=C2=A0 I p=
referred 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 t=
oo much, and I think I'll prefer Opus. Unfortunately my search for a good f=
ree 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
