Some Tamil movies (like Enthiran or 2.0 ) were released on Blu-ray with 24-bit DTS-HD Master Audio tracks. Ripping these to MP3 is labor-intensive but yields the highest quality available.
Digital remastering is the process of re-mastering a previously released audio recording to improve its sound quality. This is achieved by re-examining the original master recording and applying modern audio processing techniques to enhance the audio fidelity. 24-bit digital remastering is a specific type of remastering that involves converting the original audio data to a 24-bit format, which offers a higher resolution and greater dynamic range compared to the traditional 16-bit format. 24 Bit Digitally Remastered Tamil Mp3 Songs Download
