Interesting modular type app arrives today:
As the name tells, Audio Lab provides a flexible platform for experiencing the fun of audio world. It can help you experiment with various audio modules(generator, filter, envelope, etc) and connect them to each other without restriction.
Audio Lab is more than a synthesizer, it is a living environment. With a few taps of adding and managing modules, you can get a unique audio instrument.
Audio Lab provides you a virtual keyboard with 3 octaves, which is enough for testing the sound you make and have fun in playing notes.
Audio Lab now provides modules such as generator, filter, envelope, delay, etc. More types of modules and features will come with future development.
