Difference between a REAL sampler and a "sample player".

As of yet, unfortunately I don't know any real sampler projects using the Arduino. Atleast in my book, a real sampler have a record function (hence the word "sampler", but the most important feature: a wave-form editor to trim them samples!!

Please tell me I'm wrong, please tell me there is such a project existing. And please let it have a sequencer as well :grinning:

A couple of problems... The Arduino doesn't have enough memory, the ADC is a little slow (for high-quality audio) and it's only 10-bits, and there is no DAC for playback. (A sample player can use an audio shield with it's own memory, DAC, and clock, etc.)

please tell me there is such a project existing.

Such a project does not exist.

The Arduino is only a controller and while the processing power is the same as a late 1980's computer their is not as much memory and no display. Adding any sort of display eats up most of your memory so you are limited as to what you can do with it.

Neither do I.

The Arduino Due is capable of recording and, with dual DACs, playing back reasonable audio, but you'd need to stream recorded audio to some external memory. It does have a total of 96k or RAM, but at, say, 32Khz sampling that's only a couple of seconds.

So, it is possible - but you'd have to write it yourself :o

The Audio Hacker shield allows you to sample audio signals and do lots of DSP projects. The sample duration depends upon the sample rate and bit depth. It uses SRAM chips to store the audio data, as well as a 12-bit ADC, 12-bit DAC, and opamp.

(full disclosure: this is my product. It's been available for over 4 years and many people have built awesome projects with it.)
