Dear all seewavers,
I'm trying to calculate a mean PSD value from each .wav file inside a folder with many sound files. I'm using seewave to calculate this but having trouble finding a nice result for my further analysis. This info will be used to characterize an urban soundscape coupled with other acoustic indices.
library(seewave)
audio_files <- list.files("path_of_my_files", full.names = TRUE)
# PSD_function
calculate_psd <- function(file) {
audio_files <- list.files("path_of_my_files", full.names = TRUE)
# PSD_function
calculate_psd <- function(file) {
snd <- readWave(file)
psd <- spec(snd, plot = FALSE, PSD = TRUE)
return(psd)
}
# create a list
psd_list <- list()
# calculate PSD for each file
for (file in audio_files) {
psd <- calculate_psd(file)
psd_list[[file]] <- psd
}
Here is where I get lost. How do I calculate and save the mean PSD value for each .wav file?
If anyone can help me with this I will be very much appreciated!!
all be best,
