    At a minimum, a Clock Source Entity must implement Sampling Frequency Control GET RANGE and GET CUR requests (ADC-2 5.2.5.1.1) in compatible USB Audio 2.0 hardware. The Sampling Frequency Control GET RANGE request returns a list of subranges (ADC-2 5.2.1). Each subrange describes a discrete frequency, or a frequency range.

Fundamentals of USB Audio - EDN

    https://www.edn.com/fundamentals-of-usb-audio/
    In USB Audio each transfer always carries a whole number of samples; alternating transfers carry 48 and 40 bytes (6 and 5 stereo samples), so that the average rate works out as 44.1 bytes per transfer. A single isochronous transfer can carry 1024 bytes, and can carry at most 256 samples (at 24/32 bits).

USB 2.0 full speed audio class max sampling frequency?

    https://electronics.stackexchange.com/questions/391130/usb-2-0-full-speed-audio-class-max-sampling-frequency
    USB1.1 frames have a length of 1ms, and isochronous transfers may put up to 1023 bytes into a frame. This gives you roughly 170 stereo 24bit samples per frame – a 170ksample/s rate.

What is the best audio sampling frequency - LmK Music ...

    https://lmkprod.com/best-audio-sampling-frequency/
    The best sampling frequency is 2 times the frequency of the highest frequency of your incoming signal. Which, in case of music, is 20.000 Hz (20Khz). Therefore: 2 x 20.000 = 40.000. There we go: the best frequency for audio sampling is around 40Khz. And talking about industrial standards, we have the mighty 44.1 Khz at our disposal. Summarizing:

    I work with audio using an external audio usb interface running at 44.1k. Windows is changing it to 48k for some reason... so I have to set Windows sampling rate to 44.1k to match my external audio usb interface (scarlett 18i20). But I cannot access any page where I can do that inside windows. As u can see in the screenshot, "Playback/Speakers" have no advanced tab to …

sampling rate of usb device | Microchip

    https://www.microchip.com/forums/m455620.aspx
    According to MAPS, the 18F USB parts can do 100ksps except for the 2553 series of 12bit A/D controllers which are limited to 50ksps. USB PIC24's can do 500ksps and PIC32's can do 1000ksps. The bottleneck for sending the data through USB is more the overhead of the interrupt required to read the samples.

Technical Note TN2274: USB Audio on the Mac

    https://developer.apple.com/library/archive/technotes/tn2274/_index.html
    On high speed USB devices, each USB frame is split into eight 125 microsecond segments called microframes. Endpoints can specify the polling interval at which transfers can occur, i.e. every microframe, every other microframe, etc. This frequency must be taken into account when calculating the max packet size.
