Audio plays in the mess and with drops when I use .mp3, is set when I convert it into .wav. Someone knows why?

I have audio files I import into AE, wishes to use. MP3s, but have a problem with them playing in the mess and most of the audio plays do not at all. Also the sound that plays does not match the waveform.

I have batch save files as .wavs to the difficulty. But I was wondering why this is happening.

In order to better clarify the MP3 format is highly compressed and has been designed to provide a faster reading on a network. Format takes all samples and looking for similar values, so he doesn't have to store each bit of data for each sample. Then a table is built which said the sample currently has the same values as the sample at that time there. This table is parsed by your CPU and audio is reassembled into sound kinda sorta corresponding to its original. The higher data further reading is to the original.

When AE leans on a MP3 player and start decoding of information, combining this with the other audio that may or may not be compressed, and mix all these calculations with the treatment effects and pixel data, MP3 decoding was sometimes out of sync simply because there is no comprehensive audit in MP3 format which ensures that the audio stream is rendered in the correct order when in the CPU clock cycles are overloaded with other processes. An MP3 player can even skip and stutter when played on an iPod, if you are at the limit of storage and execution of something else in the foreground.

Any lossless or uncompressed audio format does not work like that. Sample 1 contains all the data for this moment, sample 2 too and so on. There is no audio samples that does contain all the data so that things don't get out of use when the CPU is stress because they cannot (or at least, it's much more difficult).

It goes the same for video streams highly compressed in the production pipeline. You will always have better results if you convert to a frame without loss or close based lossless format.
