Temporal Noise Shaping (TNS) is a technique for reshaping the quantization noise over time (hence the term "Temporal"). The objective is to reduce artifacts in transient and speech signals. TNS was introduced into MPEG-2 AAC. TNS is not available in MP3. TNS is not applied for short blocks, only for long blocks.
