1/// Macro for audio unit snapshot testing
2///
3/// This macro processes an audio unit with the given configuration,
4/// generates an SVG visualization, and asserts it against a stored snapshot.
5///
6/// ## Examples
7///
8/// ```
9/// use fundsp::prelude::*;
10/// use insta_fun::prelude::*;
11///
12///
13/// // With a custom name
14/// let unit = saw_hz(220.0);
15/// assert_audio_unit_snapshot!("doc_sawtooth", unit);
16///
17/// // With input source
18/// let unit = lowpass_hz(1000.0, 1.0);
19/// assert_audio_unit_snapshot!("doc_lowpass", unit, InputSource::impulse());
20///
21/// // With input source and custom config
22/// let config = SnapshotConfigBuilder::default().num_samples(512).build().unwrap();
23/// let unit = highpass_hz(2000.0, 0.7);
24/// assert_audio_unit_snapshot!("doc_highpass", unit, InputSource::sine(100.0, 44100.0), config);
25/// ```
