    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" class for starters...

    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 intend to do just...

    Teik replied to a thread Arbitrary sized mixers in Audio Projects
    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 think is Teensy 3.2 and...

    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 patchcords to stitch...

    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 these devices are...

    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) after watching his...

    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 goes, one swallow...

    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 found issues with that...

    Teik replied to a thread Oscilloscope advice in Project Guidance
    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 doesn't take up much...
