baRulho 2.1.6

baRulho 2.1.5

new argument freq_range in synth_sounds() to limit the frequency range of modulated sounds
new function spot_ambient_noise() to find segments of ambient noise to be used as reference by other functions
new argument seed in add_noise() to let users set a seed for reproducibility (or not)

Improve error messages for functions working with master annotations
Remove requirement of “sound.id” column in add_noise() and signal_to_noise_ratio()
Fix bug in add_noise() in which ‘…’ were not sent internally to signal_to_noise_ratio()
Improved error message when missing columns in supplied Y data frames

Fix bug in find_markers() and manual_realign() when missing one marker that is not used

Improved tracking of progress messages when more than 1 progress bar is used by a process

Update requested by CRAN to fix package reference issue. No changes in the code.

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
new function plot_aligned_sounds() to visually assess precision of test sound alignment
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

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’

warbleR::freq_range_detec() is now used internally to detect frequency range of markers in master_sound_file()

New argument ‘marker’ in align_test_files() to control if the start or end marker is being used for aligning
Fix bug when detecting several templates per sound file in search_templates()

Windows length is converted to even in all functions
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

New function search_templates() to find signals in re-recorded sound files
New function align_test_files() to set time of signals in aligned re-recorded files
Parallel available on internal prep_X_bRlo_int() function
Data frame are also returned by most functions
