Hello,
I have a question, which loss encode (vorbis, lame, ecc..) sound like (near them) a lossless format and with which bitrate?
Can you make a comparison based on your opinion of various format?

 

[Pootis]

The format does not matter much, just use a high bit rate.

Opus is the best.

Opus is the best.

 
Notice that the x-axis stops at 128kb/s. There and above it's pretty much a toss-up which performs better.

Right. After that bitrate matters more than format.

Heard the sample on Opus site and it is very clear the difference between lossless and loss in Tom's Diner song

At what bitrate?

At what bitrate?

At 128 KB the sample on opus site is different from the lossless one, there aren't other samples at higher bitrate

 

[cjl]

Ahh. 128k is still a pretty poor bitrate, so it's not surprising you can hear a difference. Most people here would recommend using 256k or 320k if you wanted to listen to music in a lossy format, as those should be pretty much indistinguishable from 1411k wav.

Opus seems to be made only for low bitrate but I could be wrong

Actually to my ears Opus 128 (it's variable so sometimes as high as 150) is pretty transparent for anything I've actually bothered to ABX. Are you listening to the examples here?:

Yes here

Pretty much any decent codec can sound good at higher bitrates.  And they all tend to converge in subjective quality as the bitrates rise.
 
But the mark of a good codec is how it sounds at low-to-mid bitrates.

But two years ago for example opus was good only for low bitrate, at high bitrate it wasn't efficient. I don't know if now is different

Yeah, it's different now:
 
Opus can handle a wide range of audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It can scale from low bitrate narrowband speech to very high quality stereo music. Supported features are:

1. Bitrates from 6 kb/s to 510 kb/s
2. Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband)
3. Frame sizes from 2.5 ms to 60 ms
4. Support for both constant bitrate (CBR) and variable bitrate (VBR)
5. Audio bandwidth from narrowband to fullband
6. Support for speech and music
7. Support for mono and stereo
8. Support for up to 255 channels (multistream frames)
9. Dynamically adjustable bitrate, audio bandwidth, and frame size
10. Good loss robustness and packet loss concealment (PLC)
11. Floating point and fixed-point implementation
