## Filters
| Filter | Native Sample Format | Notes |
|:-------------:|:---------------------:|:---------------------------------------------------------------------------------------------------------------------------:|
| Resample | `float32` | Changes input source sample rate to a different sample rate.<br/>If source sample rate equals `sampleRate`, returns source. |
| Source Format | `float32 int16 int32` | Changes input source to a different format. |
| Buffer | `float32 int16 int32` | Makes output source a buffered channel of the specified size. |
| Block Size | `float32 int16 int32` | Adjusts input source blocks to a normalized block size. |
| Real Time | `float32 int16 int32` | Outputs enough samples per second equal to the source sample rate. |
| Volume | `float32 int16 int32` | Adjusts volume of all samples equally.<br/>If `adjustement` equals `1.0`, returns source. |
| Stereo | `float32 int16 int32` | Makes input stereo.<br/>If source channels equals `2`, returns source. |
| Mono | `float32 int16 int32` | Makes input mono.<br/>If source channels equals `1`, returns source. |
| ReplayGain | `float32 int16 int32` | Creates a Volume filter with the specified ReplayGain parameters. |
| Normalization | `float32` | Automatically adjusts volume according to short term audio loudness. |
### Filter Chain
Allows chaining different filters together where one's output is the next one input.
## Hashers
Several audio Analyzer hashers are implemented. List of current ones:
* CRC32
* SHA256
* SHA1
* MD5
* AccurateRipV1
* AccurateRipV1 (Start mode)
* AccurateRipV2
* AccurateRipV2 (Start mode)
## Dependencies
