Ruido 1.2.2

• Standardized function names across the package. Previous function names have been removed and replaced with the following:
  • activity -> ACTspec()
  • bgNoise() -> BGNspec()
  • bgn -> BGN()
  • singleSat() -> SAT()
  • soundSat() -> soundSAT()
  • soundMat() -> soundMAT()
  • multActivity() -> soundACT()
• Standardized the noise.matrix S4 class to always include @path and @wl slots
• Reverted the global maximum normalization introduced in version 1.2.1. Spectrogram frames are once again normalized independently within each temporal bin, consistent with the original methodology
• Bug fixes:
  • Fixed histogram bin calculation in BGN() to prevent BGN values from being overestimated by half a bin
  • Fixed an issue in BGN() that caused the lowest histogram bin to be omitted during BGN value tabulation
  • Fixed an issue in BGN() where dbRef was hardcoded to -10, preventing the user-specified value from being properly applied
• Updated documentation to use standardized index names (e.g., BGNsp, POWsp, etc.)
• Expanded function examples with additional audio signals generated using the tuneR package

Ruido 1.2.1

• Added the saveNoise argument to batch processing functions (soundSat(), soundMat() and multActivity()), allowing internally generated noise.matrix objects to be included in the output. Defaults to FALSE to preserve the output structure of previous versions. This argument is also inherited by satBackup()
• Updated batch processing functions to no longer automatically delete backup files after processing, leaving their management to the user
• Improved the processing speed of activity() and singleSat() through the use of matrixStats functions and vectorized operations
• Moved DC offset correction outside the time-bin processing loop, improving both performance and implementation of the algorithm
• Bug fixes:
  • Fixed EVNspec() returning one fewer row than expected in noise.matrix@values
  • Fixed histogram bin calculation to prevent BGN values from being overestimated by half a bin
  • Fixed decibel conversion so that spectrogram frames are no longer normalized independently by their individual maximum amplitudes. A single global maximum is now used for the entire spectrogram
• Documentation updates:
  • Corrected the height description in sampleBGN() from 4’11” to 1.5 meters
  • Fixed documentation typos
  • Fixed function masking in bgNoise() examples
  • Added the missing @slot documentation for noise.matrix

Ruido 1.2.0

• Added matrixStats dependency for efficient matrix operations
• Removed signal dependency; spectrogram and window generation are now implemented natively
• Added two new acoustic index functions:
  • bgn() for Summarized Background Noise and Soundscape Power
  • EVNspec() for the Spectral Acoustic Event Index
• Added the dbRef argument to functions that perform decibel conversion, allowing users to specify the decibel reference. The default is 10, so existing results remain unchanged
• Reworked normHandler() to eliminate user prompts and automatically select an appropriate normality test based on the number of files
• Improved bgNoise() processing performance by:
  • Reducing unnecessary data conversions
  • Using the matrixStats package to optimize matrix calculations
  • Making object formatting more efficient when the input is an S4 object
  • Implementing C code for more efficient spectrogram matrix calculation
  • Vectorizing histogram breaks calculations
• Updated and expanded function documentation, including:
  • Adding the decibel conversion formula to bgNoise().
  • Specifying “Spectral” in the titles of relevant spectral acoustic indices
  • Documenting the normality tests accepted by the normality argument

Ruido 1.1.1

• Updated activity() to output a noise.matrix object
• Updated singleSat() to accept noise.matrix objects produced by activity()
• Added examples and documentation clarifying the use of activity() together with singleSat()
• Fixed a bug in the plot() method for noise.matrix objects, where the annotate argument was being ignored

Ruido 1.1.0

• Updated package sub-title and description to better reflect current and future development focus
• Added two new acoustic index functions:
  • ACIspec() for Spectral Acoustic Complexity Index
  • ENTspec() for Spectral Temporal Entropy Index
• Removed native .mp3 file support. Users can convert .mp3 to .wav or load as tuneR Wave objects beforehand
• Migrated primary WAV file reading from tuneR::readWave() to wav::read_wav() for improved performance
  • Full backward compatibility maintained: tuneR Wave objects continue to work as input
• Improved error handling across all functions for clearer user feedback
• Fixed logical errors in channel handling for stereo/mono audio processing
• Removed redundant code and unused variables
• Cleaned up batch processing functions (removed explicit gc() calls since R manages memory by itself)
• Enhanced internal helper functions to support new and future acoustic indices
• Updated documentation throughout

Ruido 1.0.3

• Added noise.matrix object and associated methods to improve function output handling
• Added two internal helper functions for error handling and normality testing:
  • argHandler()
  • normHandler()
• Added the DCfix argument across all functions to allow users to optionally skip DC offset removal
• Added sample dataset sampleBGN for testing
• Added package testhat to package suggests
• Updated the timeBin argument to actually accept NULL (#10)
• Updated singleSat() output to be consistent when working with both stereo and mono files (#11)
• Moved all auxiliary functions to a single file

Ruido 1.0.2

• Added functions:
• activity()
• multActivity()
• Updated the output of already existing functions to include channel, normality statistics and path to audio. New functions also follow the same output pattern
• Added extra examples to show more of the package’s utilities. Also updated existing examples to accommodate the changes made to the outputs
• Greatly reduced the number of lines by improving how audios are processed and managed inside the functions
• Improved error handling for all functions
• Overall documentation improvements

Ruido 1.0.1

• bgnoise(), soundSat() and soundMat() now have better mono audio files handling
• In soundSat() and soundMat() warnings messages will no longer be included in the output
• satBackup() can now continue an unfinished process of soundMat()
• Removed the spelling package from suggests

Ruido 1.0.0

• This is the initial CRAN submission.

• Functions:

  • soundSat()
  • singleSat()
  • bgnNoise()
  • satBackup()
  • soundMat()
