baRulho 2.1.0
=========================

## NEW FEATURES

* new function `add_noise()` to modifying signal-to-noise ratio by adding synthetic noise
* new function `manual_realign()` that generates an interactive plot for manual adjustment of time alignments
* new function `plot_blur_ratio()` that generates plots previously created by `blur_ratio()` and `spectrum_blur_ratio()`
* new function `plot_degradation()` to visually compare sounds across distances

* `align_test_files()` now can take several markers as input and select that with the highest correlation score for aligning test files
* New function `attenuation()`
* Data frames and selection tables can be used as input data
* Added new methods to `blur_ratio()` and `excess_atenuation()`
* `spectral_correlation()` and `spectral_blur_ratio()` renamed to `spectrum_correlation()`, and `spectrum_blur_ratio()` respectively

### MINOR IMPROVEMENTS

* optimize performance in `signal_to_noise_ratio()`
* `atmospheric_attenuation()` is no longer available (use `attenuation()` instead)
* Improved documentation for all functions
* Fix bug in `spcc()` and `excess_attenuation()`
* 'markers' argument deprecated in `align_test_files()`
* fix bug in `auto_realign()`
* `find_markers()` compares the time difference between markers to that in the master sound file as a measure of precision
* `find_markers()` can run several markers as templates on the same files
* 'template.rows' argument deprecated in `find_markers()`
* `spcc_align()` renamed `auto_realign()`
* `search_templates()` renamed `find_markers()`
* 'output' argument deprecated
* 'parallel' argument deprecated and replaced by 'cores'

* Fix sign error in signal amplitude measurements (`signal_to_noise_ratio()` and `excess_attenuation()`)
* New function `noise_profile()` 
* rename `snr()` to `signal_to_noise_ratio()`
* New function `tail_to_signal_ratio()` to measure reverberations
* Fix bug on `excess_attenuation()` when method = 1
* Added type argument to `excess_attenuation()` to run "Darden" version of excess attenuation
