Using R to sync up wave files e.g. podcasts

Getting audio into R:

Seewave: https://cran.r-project.org/web/packages/seewave/vignettes/seewave_IO.pdf
- Read, write, play, create time series of WAV files, convert type (wav, flac, txt).
tuneR: https://cran.r-project.org/web/packages/tuneR/tuneR.pdf
- equalWave function to compare wav files
- noSilence to trim (near) silence from start and end of audio
- periodogram to calculate spectral densities of the time series in WAV
audio: https://cran.r-project.org/web/packages/audio/audio.pdf
- Playback and control of audio files
warbleR: https://cran.r-project.org/web/packages/warbleR/index.html
- functions for comparing audio against a reference
- autodetec finds start and end of signal in an audio file
- xcorr estimates the similarity of two spectrograms by means of cross-correlation
- Acoustic (dis)similarity: https://cran.r-project.org/web/packages/warbleR/vignettes/warbleR_workflow_phase3.html
dtw: https://cran.r-project.org/web/packages/dtw/index.html
- Dynamic Time Warping: https://cran.r-project.org/web/packages/dtw/vignettes/dtw.pdf
- Computes the optimal (least cumulative distance) alignment between points of two time series.
monitoR: https://cran.r-project.org/web/packages/monitoR/index.html
