In maRce10/baRulho: Quantifying (Animal) Sound Degradation

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
• 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

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'

baRulho 1.0.6

• Update requested by CRAN

baRulho 1.0.5

• Update requested by CRAN

baRulho 1.0.4

MINOR IMPROVEMENTS

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

baRulho 1.0.3

• Update requested by CRAN

baRulho 1.0.3

MINOR IMPROVEMENTS

• 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()

baRulho 1.0.2

MINOR IMPROVEMENTS

• 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

baRulho 1.0.1

NEW FEATURES

• 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

baRulho 1.0.0

• First release
