# spectrophoto

Turns an image into an audio file. Image is visible on the spectrogram. 



## Building

```bash

git clone https://github.com/kylophone/spectrophoto

cd spectrophoto

gcc ./spectrophoto.c -o spectrophoto -std=c99 -lm -O3 -Wall

```

## Usage

```

spectrophoto in.jpg out.pcm 10

```

## Output

This will generate a 48k/32-bit floating point raw PCM file. You can listen to it with SoX like this:

`play -c 1 -r 48000 -b 32 -e float -t raw out.pcm`

Generating a spectrogram with SoX looks like this:

`sox -c 1 -r 48000 -b 32 -e float -t raw out.pcm -n spectrogram`
