AUDIO MP3 BITRATES
96kbs: The sound clearly lacks definition: as an example, noises are perceived as some breath. The result is comparable to a good FM radio.
112kbs: The sound seems less present and less natural than the original. The definition is a bit less good, the voice is less clear. Attacks are less spontaneous. The spatialization is different from the original recording: the sound seems to be located more far and more lower. There is however a very noticeable improvement compared to 96kbs.
128kbs: Noises are slightly less defined than the original. The violin is a bit less present and the piano attacks a bit less sharp. The voice is nearly identical to the original recording but sibilants are less pronounced. We can notice the same spatialization problem as with the 112kbs's one although there is again a good improvement compared to the 112kbs rate.
160kbs: The sound is more natural than 128kbs but the improvement is less spectacular than during the two preceding stages. The sound is different from the original, without however being possible to tell in what. The difference resides more in what we feel rather than in what we hear.
192kbs: The sound is not felt as the original recording. It is however totally impossible to tell in what.
256kbs: The sound is indiscernible from the original. It is impossible to make the difference with the original recording. However, when decoding back to wave, the file size is reduced therefore there is data loss.
320kbs: The sound is indiscernible from the original. It is impossible to make the difference with the original recording. When decoding back to wave all data is restored.
Wave: True audio. The audio remains identical to the original source.
