How do i know the digital output bit-rate from Touch?

[hankhsucc]

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

The Touch handles the usual sample rates up to 96kHz natively.
Beyond that, you need to install the EDO applet, and it will go up to 192kHz.

Thank you for the info.

But I am not asking the max sample rate supported by Touch.

I want to know the real-time sample rate from Touch.

You can see it in the webUI now playing screen.

OK. Thanks ! I can see the bit-rate on WebUI now.
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 ? Thank you !

FLAC files have a lower bitrate than wave but are lossless.

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

Thank you so much ! It is clear now.
