How Do You Improve Sound Quality Of Compressed MP3 Files?
When a file is compressed to mp3 format audio information is discarded to enable the smaller file size.. Remove too much audio info and the result is what you have now. The discarded information cannot be replaced and it’s not possible to tweak the files you have to produce a better sound. Your best option is, as suggested, try to find the same files at a higher bitrate. 128 kbps is generally regarded as the best compromise between file size and quality. 320 kbps is the highest quality bitrate but you would be unlikely to hear any difference between this and 128 kbps if only using laptop speakers. The quality you hear depends on the speakers/sound system used to listen with. Audacity has been mentioned. It’s a good program but still not up to the task. 48 – 58 kbps: Suitable for speech only. 96 kbps: Absolute minimum bitrate for music files. 128 kbps: Generally regarded as the best compromise between file size and quality. 160 kbps and up: Better quality but difference heard depends on
