First encoder for mp3PRO online
After several companies (including Microsoft) have tried to find an alternative to MP3 that should offer even better sound with less file volume, the official successor, mp3PRO, commissioned by Thomson, is now based on a first player/encoder has been published.
The new format should achieve CD quality at a rate of 64 bit and thus deliver some smaller audio files. This is made possible by the new technology of 'Spectral Band Replication' (SBR), which is also able to reconstruct high frequency ranges that are no longer present in conventional MP3s and thus noticeably reduce the quality. The player named 'RCA Demo mp3PRO Player/Encoder 1.0' supports not only playing MP3, mp3PRO and WAV but also converting wave files into 64 bit mp3PRO. Furthermore, the player allows SBR to be switched on and off at the push of a button, thus enabling a direct comparison of the two formats. Mp3PRO is currently only available for Windows, with support for Mac and Linux to follow in July. The encoder's shareware, limited to 64 bit, can be downloaded here .
