Hi, New member here, hoping for some help. I have a DigiOne player (RPI3b+ & DigiOne), powered by the standard RPI wallwart PSU, connected to the DAC in an Audiolab 8200CD, which is connected to my hifi amp. The Audiolab DAC is capable of playing 24 bit 96 kHz files, via USB input or via SPDIF coax but I can't find any way to get the RPI/DigiOne to output sound higher than 16 bit 44.1kHz. I don't have another SPDIF source capable of outputting hi res files but I have used a windows 10 laptop via USB connection to achieve 24 bit 96kHz (which

How could it happen that audio file's bitrate is 1024kbps but it has 44.1 kHz sampling frequency at 16 bits. 44.1(kHz) * 16(bits) = 705.6 kbps. Is it not? Am I missing something ?

Dear fellow audio enthusiast, Today I published a first draft of mpd-monitor, a minimal load and realtime monitor of an audiostream as handled by mpd. A screencast says it all: Details and documentation are available at the gitlab repository: https://gitlab.com/ronalde/mpd-monitor/. When you experience bugs or issues, which will be the case, please submit those in the gitlab project. I would like to hear your thoughts. Happy listening and monitoring, Ronald

Interested in the facts? One of the world’s top converter designers Dan Lavry has written a new paper in simple language to demystify the subject. http://www.lavryengineering.com/pdfs/lavry-white-paper-the_optimal_sample_rate_for_quality_audio.pdf See why many professional engineers still work at 96kHz years after 192kHz became available. Find out why “more” is not always “better!”

I have a long history in telecom so I understand the concept of sampling an analog signal and turning it into a digital stream. Perfect example is the early 64K channels in T1's for voice (sample 2x highest frequency and create 8 bit word or each sample (8000Hz * 8 bits = 64K channel). And obviously a digital bit-stream must be sampled at a certain rate to accurately turn it back into analog. But I am confused as to what and how up-sampling works and how it could even create a better quality analog signal from the original digital signal.
