looping in all audio files

I'm trying to remove silence in audio files I already did that in every single file but I still have thousand of another files. but to save time, how I can loop them to silence all files in the same time and be able to download all new audios?. I tried but it gets me some errors.

clc; clear all; [filenames, pathname] = uigetfile({'.wav'},'Select file .wav', ... 'MultiSelect', 'on'); fullpathnames = fullfile(pathname, cellstr(filenames)); numfiles = length(fullpathnames); audio = cell(numfiles, 1); fs = zeros(numfiles, 1); for i = 1: numfiles

[audio{i}, fs(i)] = audioread(fullpathnames{i}); end % do framing f_d = 0.25; f_size = round(f_d

fs); n = length(audio); n_f = floor(n/f_size); %no. of frames temp = 0; for i = 1 : n_f

frames(i,:) = audio(temp + 1 : temp + f_size); temp = temp + f_size; end % silence removal based on max amplitude m_amp = abs(max(frames,[],2)); % find maximum of each frame id = find(m_amp > 0.03); % finding ID of frames with max amp > 0.03 fr_ws = frames(id,:); % frames without silence % reconstruct signal audio_r = reshape(fr_ws',1,[]); plot(audio_r); title('speech without silence'); hold on; plot(audio,'r'); legend('After Silence Removal','Original Signal'); frame_analysis_silence_removal.m Displaying frame_analysis_silence_removal.m.

dir('*.wav') will return a struct containing all the audio file names. Then you can pass the name field of each element of that structure array to audioread in a for loop. That would take uigetfile out of the picture.

Can you edit it in the code please to understand

[Walter Roberson]

You should format your code first before expecting someone to edit it. With the way it is now, we cannot tell where the comments end.

Here is a small sample to try yourself and if you have problems and want to post a new sample of your code for help, you may do that.

>> cd rtwdemo_roll_ert_rtw\

>> D = dir('*.c')

D =

2×1 struct array with fields:

name

folder

date

bytes

isdir

datenum

>> D(1).name

ans =

'ert_main.c'

>> D(2).name

ans =

'rtwdemo_roll.c'

audioDatastore can simplify this type of task.

ads = audioDatastore(yourFolder);

% Read all files, one by one, using a while-loop
while hasdata(ads)
    [data,info] = read(ads);
    % do whatever you want with the data
end
