RadLight TTA DirectShow filter enables playback of TTA (True Audio) encoded files in RadLight or any other DirectShow based player.

TTA is a simple lossless audio compressor based on adaptive prognostic filters which has shown the same or the better results comparing to majority of modern analogs. Our main requirements to compressor development was the reasonable compression level and high operation speed.

TTA performs lossless compression on multichannel 8,16,24 bit's integer and 32 bit's IEEE floating-point data of the Wav audio files. Being "lossless" means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original. The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original. TTA format supports both of ID3v1 and ID3v2 information tags.
