Popular audio gadget maker Bastle just released an that lets you capture and transform audio directly from your iPhone’s speakers and microphone. Despite the slightly cringey app name, it looks pretty darned fun, allowing users to explore the ambient noise around them to create some truly unique soundscapes.
Once you capture some audio via the app, use Bastl’s latest creation to make harmonious or discordant feedback, manipulate responses, apply resonant filters and more. You can even use your mouth, speaking directly into the phone’s microphone, to create your own resonant filter.
Additionally, you can capture impulse responses from just about anything, with Bastl using a coffee cup or a construction site pipe as examples. These IRs can then be used to run other audio sources through to create custom reverbs and the like, via a DAW or a standalone piece of hardware. The only caveat here is the phone has to fit inside of the object or the space it’s capturing, so your dreams of having an impulse response from the inside of a toilet paper roll are, sadly, quashed.
The integrated media player allows for full looping and lets you adjust the start and end points. There’s also a speed slider, from ¼ speed to 4x, and a cropping function. As for the recorder, it saves wav files to pass on to other devices, again with adjustable start and end points. You can also speed match recordings, so the recorded speed automatically matches the tempo set in the player while preserving the pitch. Of course, there’s also a countdown timer so you can get in position before the app starts recording.
The audio gets transformed via a feedback pad with adjustment options for amount and tone. There’s even an adjustable delay that changes how long it takes the microphone to reach the feedback pad.
