A Subjective Evaluation of High Bitrate Coding of Music

Document Thumbnail

The demand to deliver high quality audio has led broadcasters to consider lossless delivery. However the difference in quality over formats used in existing services is not clear. A subjective listening test was carried out to assess the perceived difference in quality between AAC-LC at 320 kbps and an uncompressed reference, using the method of ITU-R BS.1116. Twelve audio samples were used in the test, which included orchestral, jazz, vocal music, and speech. A total of 18 participants with critical listening experience took part in the experiment. The results showed no perceptible difference between AAC-LC at 320 kbps and the reference.
