Guitar Effects¶

We start with a file containing audio from an acoustic guitar

In [36]:

File file = SD.open("guitar.raw", FILE_READ);

Then we can apply some effects on it

In [37]:

int channels = 1;
int sample_rate = 44100;
AudioEffectStream effects(file);

// setup AudioEffectStream
auto cfg = effects.defaultConfig();
cfg.channels = channels;
cfg.sample_rate = sample_rate;
effects.begin(cfg);

file.available()

Out[37]:

Now we can output the audio with JupyterAudio. The full audio is split up into batches of 1024 bytes

In [38]:

int siz = 1024;
int cnt = file.available() / siz;
JupyterAudio audio("guitar.wav", effects, cnt, siz);
audio
