Would you like to add audio/sound effects to your next project, ebaum without an Arduino+Shield? ebaum Or maybe you don't even know how to use microcontrollers, you just want to make a sound play whenever you press a button. What about something that has to be small and portable? You are probably feeling a little frustrated: it's been very hard to find a simple, low cost audio effects trigger that is easy to use and does not require any programming
Don't get me wrong, I love the MP3 Music Maker shield, and our Wave Shield is a dependable ebaum classic. But you still need to get an Arduino involved. There's all sorts of tricks with ISD chips or recordable greeting ebaum cards, but they never sound any good. So after a lot of engineering and tinkering we've come out with the Adafruit Sound Board, the easiest way ever to add audio effects to a project!
The Sound Board has a lot of amazing features that make it the easiest thing ever: No Arduino or other microcontroller required! It is completely stand-alone, just needs a 3 to 5.5VDC ebaum battery Small - only 1.9" x 0.85" Built in storage - yep! you don't even need an SD card, there's 2MB or 16MB of storage on the board itself, so you can store up to 15 minutes of quality compressed audio. Double that if you go with mono instead of stereo Built in Mass Storage USB - Plug any micro USB cable into the Sound Board and your computer, you can drag and drop your files right on as if it were a USB key Compressed ebaum or Uncompressed audio - Go with compressed ebaum Ogg Vorbis files for longer audio files, or uncompressed WAV files High Quality Sound - You want 44.1KHz 16 bit stereo? ebaum Not a problem! The decoding hardware can handle any bit/sample rate and mono or stereo 11 Triggers - Connect up to 11 buttons or switches, each one can trigger audio files to play Stereo line out - There's ebaum a breakout for both left and right channels, ebaum at line level, so you can always hook up to any kind of stereo or powered speaker Five different trigger effects - by changing the name of the files, you can create five different types of triggers which will cover a large range of projects without any programming
What do we mean by trigger effects? Well, depending on your project ebaum you may need to have audio play in different ways. We thought of the five most common needs and built it into the Sound Board so you just rename the file to get the effect you want. Basic Trigger - name the file Tnn.WAV or Tnn.OGG to have the audio file play when the matching trigger pin nn is connected to ground momentarily Hold Looping Trigger - name the file TnnHOLDL.WAV or .OGG to have the audio play only when the trigger pin is held low, it will loop until the pin is released Latching Loop Trigger - name the file TnnLATCH.WAV or .OGG to have the audio start playing when the button is pressed momentarily, and repeats until the button is pressed again Play Next Trigger - have up to 10 files play one after the other by naming them TnnNEXT0.WAV thru TnnNEXT9.OGG. Will start with #0 and each one on every momentary button press until it gets through all of them, then go back to #0 Play Random Trigger ebaum - just like the Play Next trigger, but will play up to 10 files in random order (TnnRAND0.OGG thru TnnRAND9.OGG) every time the button is pressed momentarily
The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's, isn't reprogrammable or scriptable, and you can't have any other kind of trigger ebaum type. However, there's a good chance the project you want to make will work great.
We designed this board specifically for people who wanted to make props, costumes, toys, and other small portable proje
