Cash Code started developing bill validators in 1991 and has continued its work with award winning products and patents.
In 2000 Cash Code introduced its first frontload bill validator and continued its developments to meet the global realization of multi-width currencies and engineered a truly automatic multi-width note alignment mechanism.
mp3 and you have AAC, you probably want to use a high bit rate to avoid as much loss as possible.
By increasing the bitrate you won't have an higher sound quality.
@Luke Put differently, converting a 96kb/s flash-audio format directly to a 96kb/s MP3 may cause additional data-loss. A 96kb/s MP3 file may destroy data present in the flash-audio version.If you have a file with 95kbps in a highly efficient format, to retain the same quality, a relatively inefficient format as mp3 needs a higher bitrate.Of course you will never get anything back that was lost in the first place.The real issue is whatever lossy scheme is applied at the encoding stage (psychoacoustic filters etc.)I don't think he expects it to be of higher quality than the input source, but wants to know if, say, transcoding a 128kbs AAC to a 192kbs or 256kbs MP3 will sound better than if he transcodes it to a 128kbs MP3.I've wondered the same thing since I have a bunch of AAC files that I sometimes convert to MP3 since the car player only understands MP3.
First it's correct that you don't get more information from up sampling.
