| 1298111 | 2012-09-04 02:13:00 | Each codec also tends to use it's own file extension to help identify the files. But not necessarily. Some file extensions only identify the "container" and the data inside could be compressed with one of many codecs. (AVI is a good example of this) |

| 1298113 | 2012-09-04 21:47:00 | I was talking about audio files which generally do have a dedicated extension for the file type. "Containers" such as .avi and .mkv are more in the Video side of things and a whole other source of confusion I wasn't going to go into. | dugimodo (138) | ||

| 1298115 | 2012-09-04 23:03:00 | Another thought that occurs to me to mention. If you want a different format or bitrate etc you should always use the original CD or a lossless format file as the source because converting between "lossy" compressed formats will result in poor quality sound. Every time you encode to MP3 or WMA, OGG etc data is lost, the compression techniques discard "unecessary data". Converting these files again loses even more data and won't sound the same as an apparently identical file format created from the original. This is especially true of low bitrate files, going from a 128kb WMA to a 128kb MP3 for example is a bad Idea. I find it amusing that as compression techniques continue to improve allowing ever smaller file sizes for good quality audio, storage technology keeps getting bigger making compression less and less necessary. I could quite easily store my CD collection in original uncompressed quality on a small or medium sized hard drive (and I do :)) |

Quite true, also an issue with image files such as .jpeg if you re-save you lose data, very noticeably. |
