    Sounds like about 30 minutes of work if you already have the kitten sample as an array of bytes or ints... You'll need to right a simple class derived from Audiostream. Maybe hack "synth_sine"...

    If you want dirt cheap but reasonable audio you could use the Sparkfun i2s audio breakout which would save you a lot of work (even comes with amp). It should work with the Teensy Audio library and I...

    It's basically what would happen if you concatenate a bunch of AudioMixer4 things albeit marginally faster as you don't have all the summing of mixers upon mixers. For "__ARM_ARCH_7EM__" which I...

    Arbitrary sized mixers

    If like me and you're dealing with lots of simultaneous voices (eg synth project) you're probably a bit frustrated with AudioMixer4 having only 4 inputs. Then you'll have the large cascade of...

    Elmue, why don't you ask him yourself? He's got a huge forum and specialises in test equipment more so than PJRC. I'm a happy Rigol owner so don't have an itch to scratch... You have to understand...

    Dave Jones - my fellow Aussie - on EEVblog was loaned the DS1054z he reviewed and subsequently bought one of his own. Coincidentally, I also bought it from the same company (down the road from me)...

    This is why I only buy things like that from actual brick and mortar shops I can drive to. If there's a problem with yours maybe take it back for a refund ore replacement if you can. As the saying...

    The problem seems to be only when you are using "24 megasample" capture mode as described in your stackexchange thread. Is that correct? So your scope should be still fine at 12MSP? Or have you...

    I have a Rigol DS1054z. It's close to your $300 budget. 4 channels, 50MHz. Apparently you can "software hack" it to 100MHz but I haven't needed or wanted to. It's a really nice thing to use and...

    You can add easy to use WiFi to your project with an ESP8266 for < $2. It's kinda nuts how cheap that is.

    What I find particularly amusing is you're turning into a flute into another instrument and my personal challenge was to turn a guitar into a flute! Here's Bohemian Rhapsody as played by a bank of...

    That looks really cool :-) I'm doing a guitar synth project - polyphonic tracking. But all in the digital domain. So far I'm getting 10-80Hz latency depending on the note. You're a much better...

    Do you mean band pass filters (at least for the intermediate ranges)? What are you trying to measure? How separated do you expect the 4 frequencies you are trying to measure are? It could be very...

    Are you trying to measure an external signal? If so, for minimum latency you might consider using an external comparator like an LM393 and connect it's output to a digital input. You can use a...
