SIGCONT can be handled just fine, both according to the manual, and in practice... (at least under Linux, been there, done that.)

Luckily enough, HDCP encryption is broken. You can download the verilog for a HDCP "overlay" (which, for obvious legal reasons only encrypts HDCP so that a video overlay can be put on a digital image) from: http://kosag

Music or video production studios typically have a central clock, so for this use-case the sample rates should be perfect. But even if the input and output devices are on perfect clocks, with NTSC (59.94 Hz), you'd need a very odd numb

If everything happens strictly synchronous to your audio clock, then fixed block processing is the way to go. But jblow is right in that when you have to feed in samples from a non-synchronized source into your processing/game/v

I didn't downvote you and was genuinely interested in why you were considering my information to be incorrect. And I now realize it's because I've always worked with systems where processing is always strongly synced to the c

Well... it's like all audio chipsets work nowadays. Only some DSPs will be able to efficiently handle single-frame data processing, but they have the help of dedicated address generators and lightweight interrupts synchronized to the d

The lowest possible input-to-output latency of an audio workstation is always two times the period size (samples/buffer) (plus a few microseconds of internal delays in the ADCs, controllers, ...) The sound chips operate on integral per

ALSA is not the problem, it works very fine for the low-latency case, I can reliably run soundcards with light processing load at 96 kHz @ 64 frames/period (2 0.7ms --> 1.4 ms latency) on a quad core i5, e.g. for running a reverb ef

If you just power down by running the i2c slave power through a FET, either the i2c-slave might pull down the i2c lines in an uncontrolled fashion.. or the i2c-slave might still be powered through the i2c SDA/SCL pullups. So if you re

Their products are really neat, I second your recommendation. Very handy for what they do. At work I have the legacy 8-bit-wide and the faster 16-bit-wide devices, and they've paid for themselves tenfold. And their software indeed is v

Please note that is not a universal properties of SPI devices. Only some can be daisy chained. E.g. the first google-hit I get for an "SPI ADC" is the MCP3004 that doesn't daisy-chain.

Maybe putting the musician at an elevated position, for the audience to see was the intention? I mean, you only see his back, but that would also be the case if the instrument would be turned upside down.

Nils Frahm has just released an album recorded on this instrument. It's downloadable at http://www.pianoday.org/ for free, but donations are said to go into a fund to build the even bigger successor.

A Gigabit Ethernet PHY has to do quite some signal processing (line equalization) for its normal function. And there are a few chipsets that allow you to inspect the link parameters in quite some detail. For example, have a look here for sc

I can't believe how long muscle-memory can persist! I started programming in DOS in the 90s, and just hitting Ctrl-H in joe makes my muscles remember the most-used chords... A very funny flashback.
