Functions

func CSV

func CSV(buf *audio.PCMBuffer, path string) error

CSV writes the content of the buffer in a CSV file. Can be used to plot with R for instance:

Rscript -e 'png("my_plot.png", height = 768, width = 1024);
myData <- read.csv("./data.csv"); matplot(myData[,1], type="l")'

func GnuplotBin

func GnuplotBin(buf *audio.PCMBuffer, path string) error

GnuplotBin exports the buffer content as a binary gnuplot file.

func GnuplotText

func GnuplotText(buf *audio.PCMBuffer, path string) error

GnuplotText exports a gnuplot compatible text file for plotting. After normalizing the data (for better plotting) and exported it, you can use gnuplot command line, for instance:

gnuplot -e "plot 'my_data.dat' with line"
