I think you are mixing up "sample rate" and "bit rate" Sample rate is the number of audio sample per sec to make up audio stream e.g. CD 44,100 16 bit samples The audio stream of a specific sample rate can then be compressed (lossy or lossless) into data stream of bits which has a data rate or bit rate (i.e. kbits/sec). The slower the data rate the greater the compression. Bit rate was important was using live stream such with digital radio DAB or TV DVB as player had no buffers - bandwidth of transmission medium (e.g. satellite, terrestrial) restricted data rate of compressed audio stream of typically 44.1Khz / 48kHz 16 bit. Touch is a buffered played so data is sent in bursts so bit rate is not sdignificant. Touch will decode the data streams and output the audio sample rate of the data streams - realtime audio sample rate of 44.1Khz 16 bit will be sent from digital output regards of whether the data source is PCM - 1411k Flac - about 700kb (can vary according to compression level ) MP3 - typically from 32kbs up to 320kbs CBR will have a maximum data rate, VBR will be varying but an average data rate as speced - again the realtime audio sample rate after decompressing will be same as source 44.1Khz 16bit bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=113074 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

But all my music files are Redbook CD ripped by "Exact Audio Copy" in lossless FLAC compressed mode. It is supposed the bit-rate be 1411k CBR, but what the WebUI shows is various bit-rate (VBR) under 1411k. For example, 640K VBR, 712K VBR, ... Why ?

The Touch handles the usual sample rates up to 96kHz natively.

Since my dac doesn't come with display of input bit-rate, can I have the digital output bit-rate from Touch ?
