Can you elaborate on what you mean by "crunchy" for example i wouldn't consider a bitcrusher crunchy.it just raises the noisefloor via quantization distortion and samplerate reduction adds aliasing.maybe provide an example
When I say crunchy I'm referring to a fairly distorted/fairly high end-ish sound. Like imagine recording a potato chip bag on an iPhone 4, putting it through a waveshaper, and boosting the highs on the recording. If you just play with the "Number of bits" knob and the "DA Aliasing" knob on TB Timemachine you can get a pretty distorted/clipping-type sound (with a fair bit of noise generated by the plugin). Maybe crunchy is the wrong word for what I'm getting at, but it's the best word I could think of for what I was describing. Sorry if what I said wasn't clear dude!
Well decreasing the bits would just make the difference between the signal and the noise less great and an Iphone is likely to have a pretty shitty signal to noise ratio to begin with so you may aswell just record the sound allot quieter so the noise floor comes up sooner through processing
Putting a naturally granular sound through a waveshaper (i.e potato crisps per your example) would destroy what made it granular to begin with,especially a waveshaper because when they crest they don't do a very good job of retaining the transient events,you could try something like attaching an envelope follower* to the pre-gain but if the envelope follower* operates at a control rate (a predefined ppq amount) ,it's not gonna do a very good job at catching those tiny tiny discreet transients within the sounds and will probably click unpleasantly
your best option would be just layer that quality on top of a sound and bring it up through upwards dynamic processing and minor saturation to homogenise the 2 sounds
There's more possibly exotic methods involving outboard,but i'm presuming this is a primarily digital forum
