Macro for audio unit snapshot testing

This macro processes an audio unit with the given configuration, generates an SVG visualization, and asserts it against a stored snapshot.

Examples

use fundsp::prelude::*;
use insta_fun::prelude::*;

// With a custom name
let unit = saw_hz(220.0);
assert_audio_unit_snapshot!("doc_sawtooth", unit);

use fundsp::prelude::*;
use insta_fun::prelude::*;

// With input source
let unit = lowpass_hz(1000.0, 1.0);
assert_audio_unit_snapshot!("doc_lowpass", unit, InputSource::impulse());

use fundsp::prelude::*;
use insta_fun::prelude::*;

// With input source and custom config
let config = SnapshotConfigBuilder::default().num_samples(512).build().unwrap();
let unit = highpass_hz(2000.0, 0.7);
assert_audio_unit_snapshot!("doc_highpass", unit, InputSource::sine(100.0, 44100.0), config);

use fundsp::prelude::*;
use insta_fun::prelude::*;

// With unit and config
let unit = lowpass_hz(1000.0, 1.0);
let config = SnapshotConfigBuilder::default().num_samples(512).build().unwrap();
assert_audio_unit_snapshot!(unit, config);
