## Calculate all possible difference and combinations tones

### Description

Determine all possible difference and combinations tones from a set of frequencies, and find the closest one to a specified frequency

### Usage

```
tones(a=NULL,freqs=NULL,f=T)
```

### Arguments

`a` |
The frequency you are seeking to match, in cycles/ka. |

`freqs` |
The vector of frequencies from which to calculate difference and combination tones, in cycles/ka. |

`f` |
Output results as frequencies (cycles/ka)? If false, will output results as periods (ka). (T or F) |
