# iOS - Concatenate or generate audio
Build in support for `.mp3`, `.m4a` and `.wav` input audio files.
### Usage
Add module:
```
var AudioMerger = require('com.composrapp.audiomerger');
```
Specify audioMergeType, audioFilesInput and audioFileOutput argumnets:
**audioMergeType**
Use `concatenate` or `generate`.
**audioFilesInput**
Concatenate example:
```
var concatenateAudios = [
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '1.mp3').nativePath,
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '2.mp3').nativePath,
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '3.mp3').nativePath
].join();
```
Generate example:
```
var generateAudios = [
{ audio: Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '140-drum.mp3').nativePath, timings: [0, 14000, 28000] },
{ audio: Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '140-guitar.mp3').nativePath, timings: [0, 14000, 28000, 42000] }
];
```
If the `bpm` argument is provided to `mergeAudio({ bpm: 140 })`, `timings` will be handled as **notes**. When `bpm` is not specified they will be handled as **milliseconds**.
**audioFileOutput**
Should always end with `.m4a`.
Example:
```
var concatenatedAudio = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'example.m4a');
```
**mergeAudio**
Concatenate audio:
```
AudioMerger.mergeAudio({
audioMergeType: 'concatenate',
audioFilesInput: concatenateAudios,
audioFileOutput: concatenatedAudio
});
```
Generate audio:
```
AudioMerger.mergeAudio({
audioMergeType: 'generate',
audioFilesInput: generateAudios,
audioFileOutput: generatedAudio
});
```
**eventListeners**
```
AudioMerger.addEventListener('concatenate', function() {
Ti.API.info('Concatenated audio');
});
AudioMerger.addEventListener('generate', function() {
Ti.API.info('Generated audio');
});
AudioMerger.addEventListener('error', function() {
Ti.API.error('Failed to merge audio');
});
```
## Examples
Concatenate example:
```
var concatenateAudios = [
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '1.mp3').nativePath,
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '2.mp3').nativePath,
Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, '3.mp3').nativePath
].join();
var concatenatedAudio = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'example.m4a');
AudioMerger.mergeAudio({
audioMergeType: 'concatenate',
audioFilesInput: concatenateAudios,
audioFileOutput: concatenatedAudio
});
AudioMerger.addEventListener('concatenate', function() {
Ti.API.info('Concatenated audio');
});
```
Generate example:
```
var generateAudios = [
{
audio: Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, '140-drum.mp3').nativePath,
timings: [0, 14000, 28000]
},
{
audio: Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, '140-guitar.mp3').nativePath,
timings: [0, 14000, 28000, 42000]
}
];
var generatedAudio = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'example.m4a');
AudioMerger.mergeAudio({
audioMergeType: 'generate',
audioFilesInput: generateAudios,
audioFileOutput: generatedAudio
});
AudioMerger.addEventListener('generate', function() {
Ti.API.info('Concatenated audio');
});
```
Generate example by BPM:
```
var generateAudios = [
{
audio: Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, '140-drum.mp3').nativePath,
timings: [64, 128, 192]
},
{
audio: Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, '140-guitar.mp3').nativePath,
timings: [0, 64, 192]
}
];
var generatedAudio = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'example.m4a');
AudioMerger.mergeAudio({
audioMergeType: 'generate',
audioFilesInput: generateAudios,
audioFileOutput: generatedAudio,
bpm: 140
});
AudioMerger.addEventListener('generate', function() {
Ti.API.info('Concatenated audio');
});
```
### Development
1. Install packages with `npm install`
2. Update examples in `example/app.js`
3. Use `gulp ios` to build and test the module
