Do you want to add sound/audio effects in your next project? Without Arduino and without shield? Or maybe you don't know how to use a microcontroller? Maybe you just want to play an audio file by pressing a button. Do you want something small and portable?
If you were looking for such a product: know that there is a simple and affordable solution capable of triggering audio effects (files) without any need for programming :-)
Don't misinterpret our words. We love the MP3 Music Maker Shield, just like the classic Wave Shield we can always count on. However, they both need an Arduino to work. There is a lot of component type ISD (recording solution and listening on a chip) and recordable greeting board but the quality of the sounds is often deplorable. After a long period of design, AdaFruit has tried to produce the best sound effect board possible... enough to quickly add sound effects to your projects! Finally, this board is certainly the best soundboard (audio effect) for accessories and costumes!
This version of the board DOESN'T HAVE an amplifier! If you don't need a version with amplifier then see the version with amplifier.
This product includes the Audio FX soundboard, a connectors row. It doesn't include batteries, speaker, breadboard or touch buttons.
The board has plenty of incredible features making this board the easiest to use:
- No need for Arduino or microcontroller! This board is completely autonomous. You just need a power supply between 3 and 5.5V continuous.
- Incredibly small - with its 48.3 x 21.6mm, it can fit almost anywhere.
- Integrated storage space - great! You don't even need an SD card, this board has 16MB of memory on the board. That's enough to store a few minutes of compressed stereo, and maybe half a minute of uncompressed stereo. Double if you use mono sound instead of stereo. If you don't need so much storage space, there is also a version of this product with 2MB Flash.
- USB mass storage device - connect a micro USB cable to the sound board and the other end to your computer, you can then copy/paste directly to the board as if it were a USB stick.
- Compressed and uncompressed audio - use compressed Ogg Vorbis files to have longer records, or WAV files for uncompressed files.
- High Quality Audio - Want to use stereo files in 44.1KHz 16 bis? No problem! The hardware is able to handle all sample and bit rates, in mono and stereo (see description AdaFruit)
- 11 triggers - connect up to 11 buttons or switch, each of them can trigger an audio file to play.
- Stereo output line - Headphones, speakers (with power supply) or even one of the amplifiers available to make more noise. We also have a version of this product with an integrated amplifier.
- 5 different triggering effects - by changing the name of files, you can create 5 different types of triggers. This should cover a large part of the projects without the need for programming.
What does these "trigger effects" mean?
The "trigger effects" helps determine how the audio is played. Indeed, depending on the nature of your project, audio files should be played in one way or another. AdaFruit has identified 5 different needs (most common) that are included in the sound board. You just need to rename your file to get the desired effect. See the tutorial section for more information about this.
- Basic trigger.
Name your file Tnn.WAV or Tnn.OGG to play the audio file corresponding to trigger pin nn (the pin must be momentarily connected to ground).
- Trigger with hold - in continuous loop (Hold Looping Trigger)
Name your file TnnHOLDL.WAV or .OGG to play the audio file only while the trigger pin is kept low (to ground). The file is played in a loop until the pin is released.
- Trigger on/off - in continuous loop (Latching Loop Trigger)
Name your files TnnLATCH.WAV or .OGG to start playing your file when you momentarily press the button and repeat it until you repress the button a second time.
- Trigger next file (Play Next Trigger)
Have up to 10 files to play one after the other by naming them TnnNEXT0.WAV to TnnNEXT9.WAV (or .OGG). Start with file #0 and each of the following with each press of the button. When the last file is played then it starts again with file #0
- Random trigger (Play Random Trigger).
Operation identical to the previous case except that the file is chosen randomly between files #0 to #10. Name your files TnnRAND0.OGG to TnnRAND9.OGG (or .WAV). The trigger occurs each time a button is pressed.
The soundboard is designed to be simple: it doesn't have polyphonic functionality, doesn't play MP3 files (MP3 is patented and the license is paid for. The board uses a similar OGG format but free/non-patented, there are many free conversion software to convert MP3 to OGG). The board isn't reprogrammable or scriptable and it isn't possible to obtain other types of trigger (however, there is a good chance that the features available are perfectly suited to your project).
AdaFruit has specially designed its product for makers who want to make accessories, costumes, toys and other small portable projects. See the tutorial for all power options. You can power the board from 3 to 5V DC or a 3xAAA battery pack or a Lipo battery (see our power supply section), it will work well.
You can even use the Lipo for Trinket backpack that will be placed above this special effect board all in one.
