The only thing that is in stereo on MP3s are the instruments which have been panned hard on either channel but these are often ‘rolled-off’ as discussed earlier. As well as aliasing, MP3s often take both stereo channels and blend the information which is identical on both channels into one – limiting accuracy and the true stereo effect. This is problematic on many systems as you can here an often metallic sound, referred to by professionals as ‘aliasing’. MP3 files are also renowned for giving a digital sound at the high-end where they have cut-off the data.

However, MP3 is still more than adequate for a portable player designed for playing-back MP3 files.Ī visual comparison of an original, lossless file and a compressed copy. This is why MP3 isn’t ideal on a fully-fledged Hi-Fi system. This is because MP3 compression smoothes out any audio peaks and rolls them off – giving a much lesser response. But, take this principle across the entire audio track and you’ll soon here it sounds dull or flat at the high-frequency end.

An example of this would be on a drum kit’s cymbals: a CD would give the full range of the cymbal that was recorded, from the start of its sounding, until the end an MP3 would only play-back the most audible part of the cymbal’s audible sequence. This means that details in the stereo field will be missing, along with data (information that makes-up the audible) sound could be missing in the spectrum. However, with format compression, the MP3 file will miss some of the data that was found on the counterpart CD. This applies to a musical format by taking the audio file on a CD and making it much smaller to be able to fit in mass onto an MP3 file. This option adds additional CRC information into the MP3 file, and protects against small corruptions that may later develop due to faulty media on which the file is stored.The iPod has changed a generation of music listerners with downloading out-stripping CD sales.Ĭompression, in audio terms, is literally as it sounds: it takes an item and makes that same item much smaller than it was originally. Note: If the source file is Mono, the converted file will likely end up being Mono as well. Force means that the encoding process will force ms_stereo for all frames, which is faster. This selects if the MP3 file will be Stereo, Joint, Force or Mono. Note: Depending on what bitrate(s) are set, the encoder will set the output sample rate accordingly. Note that the number 0 will produce the highest quality and highest file size. The "Quality" option affects the audible quality of the file, with a higher quality yielding a higher file size for the resulting MP3 file. For this mode you must select minimum and maximum bitrates from the respective bitrate drop-down lists. Select this option to encode the audio using a variable bit rate, which is considered to produce superior results to CBR encoding. The "High Quality" checkbox option produces a better quality output but slows down the audio encoding process. The specific bitrate value can be selected from the bitrate drop-down list. Select this option to encode the audio using a constant bit rate. Output Formats - MP3 Settings Constant Bitrate Encoding (CBR)
