Thanks for signing up. There was an error. Bit rate is the resolution of your media — the higher the resolution, the better quality of your audio.

Do you need the highest possible resolution to play back silence? Of course not! Their codec varies will vary the bit rate depending on the complexity of a media segment. Silence will have a low bit rate because there is no information to relay. A loud passage with a blistering guitar solo will have a much higher bit rate because there is a wealth of information to convey. The codec will analyze segments of music and continuously adjust the bit rate according to complexity.

And therein lies the problem: the variable nature of VBR MP3s causes older media players to reject them as unsupported formats. Fortunately the solution is simple, and you can solve it in a minute or two. Without getting too technical, there is a simple way to differentiate the two in iTunes. This was specified in the original standards document in For MPEG-1 or -2 layer 2, variable bitrate decoding is optional - for layer 3, it is mandatory.

Lame is a command-line encoder it runs in DOS. You can specify literally hundreds of different options. The meaning of these VBR options is explained above in "How was this test carried out? In addition, all lame encodes were carried out using -h high quality.

In short, no! There is an unofficial tag that can be included in an mp3 to tell the decoder to true duration of a VBR file, but not all decoders understand it. However, we didn't test this feature. Go back to the list of tests or go forward to the next test. Although variable speed compressed files are difficult to stream continuously over most Internet connections, those that download the entire file before viewing are unaffected.
