Audioread error with .wav file path on windows

Hi I'm trying to read a .wav file but get an error message re the path. Have tried playing around with the '\' - what am I missing? I'm really new to MATLAB so really struggling !

FromDir= 'C:\Users\emily\Coding\vocal\output';

RawMicDir='C:\Users\emily\Coding\vocal\data';

SaveDir='C:\Users\emily\Coding\vocal\codedspeech';

filename='1001_1_1';

[Raw,Fs]=audioread(strcat(RawMicDir,filename,'.wav'));

Speakers=importdata(strcat(FromDir,filename,'.csv'));

VocDet=Speakers.textdata(2:end,1:2);

VocDet=str2double(VocDet);

savename=strcat(SaveDir,'\',filename,'coded.csv');

Error message:

Error using audioread>readaudio (line 130)

The filename specified was not found in the MATLAB path.

Error in audioread (line 123)

[y, Fs] = readaudio (filename, range, datatype);

Error in Speech_coding_Lev (line 20)

[Raw,Fs]=audioread(strcat(RawMicDir,filename,'.wav'));

Check this manually:

FromDir= 'C:\Users\emily\Coding\vocal\output';
RawMicDir='C:\Users\emily\Coding\vocal\data';
SaveDir='C:\Users\emily\Coding\vocal\codedspeech';
filename='1001_1_1';

strcat(RawMicDir,filename,'.wav')

ans = 'C:\Users\emily\Coding\vocal\data1001_1_1.wav'

% You want to insert a file separator between the folder and the path:
fullfile(RawMicDir, [filename,'.wav'])

Prefer fullfile instead of strcat.

Ahhh works thank you ! - why fullfile?

[Jan]

fullfile care about file separators e.g. to consider the operating system and to insert missing separators. Using strcat instead is a frequent source of bugs.

I see - thank you for the reply !

FromDir= 'C:\Users\emily\Coding\vocal\output';

RawMicDir='C:\Users\emily\Coding\vocal\data';

SaveDir='C:\Users\emily\Coding\vocal\codedspeech';

filename='1001_1_1';

strcat(RawMicDir,filename,'.wav')

ans = 'C:\Users\emily\Coding\vocal\data1001_1_1.wav'

% You want to insert a file separator between the folder and the path:

fullfile(RawMicDir, [filename,'.wav'])
