  • CT-Aacplus — a State-Of-The-Art Audio Coding Scheme
    AUDIO CODING CT-aacPlus — a state-of-the-art Audio coding scheme Martin Dietz and Stefan Meltzer Coding Technologies, Germany CT-aacPlus is a combination of Spectral Band Replication (SBR) technology – a bandwidth-extension tool developed by Coding Technologies (CT) in Germany – with the MPEG Advanced Audio Coding (AAC) technology which, to date, has been one of the most efficient traditional perceptual audio-coding schemes. CT-aacPlus is able to deliver high-quality audio signals at bit-rates down to 24 kbit/s for mono and 48 kbit/s for stereo signals. The forthcoming Digital Radio Mondiale (DRM) broadcasting system, among others, will use CT-aacPlus for its audio-coding scheme. CT-aacPlus will enable DRM to deliver an audio quality, in the frequency range below 30 MHz, that is equivalent to – or even better than – that offered by today’s analogue FM services. This article describes the principles of traditional audio coders – and their limitations when used for low bit-rate applications. The second part describes the basic idea of SBR technology and demonstrates the improvements achieved through the combination of SBR technology with traditional audio coders such as AAC and MP3. Advanced Audio Coding (AAC) has so far been one of the most efficient traditional perceptual audio-coding algorithms. In combination with the bandwidth-extension technology, Spectral Band Replication (SBR), the coding efficiency of AAC can be even further improved by at least 30%, thus providing the same audio quality at a 30% lower bit-rate. The combination of AAC and SBR – referred to as CT-aacPlus – will be used by the Digital Radio Mondiale transmission system [1] in the frequency bands below 30 MHz and will provide near- FM sound quality at bit-rates of around 20 kbit/s per audio channel.
