Please help to solve: Index in position 1 exceeds array bounds. Index must not exceed 1.

% Define drum sounds

open_hihat = audioread('open_hihat.wav');

closed_hihat = audioread('closed_hihat.wav');

snare_drum = audioread('snare_drum.wav');

bass_drum = audioread('bass_drum.wav');

tom_toms = audioread('tom_toms.wav');

cymbals = audioread('cymbals_sound.wav');

% Load the drum sounds into a cell array

drum_sounds = {open_hihat, closed_hihat, snare_drum, bass_drum, tom_toms, cymbals};

% Define the bpm and the number of beats in the song

fs=44100;

bpm = 130;

num_beats = 457;

% Calculate the period between two beats in seconds

period = 130 / bpm;

% Load the drum table from Table 1

drum_table = [0 1 1 1 0 0 0 1 1;

0 0 0 1 0 1 1 0 1;

0 1 0 1 1 0 0 1 1;

1 1 1 1 1 0 0 0 1;

0 0 0 1 0 1 1 0 1;

0 0 0 1 0 1 1 0 1;];

% Initialize the audio signal

audio_signal = zeros(1, num_beats * fs * period);

% Loop through each beat in the song and add the corresponding drum sounds

for i = 1:num_beats

for j = 1:6

if drum_table(j,i) == 1

start_index = round((i-1) * fs * period) + 1;

end_index = start_index + size(drum_sounds{j}) - 1;

audio_signal(start_index:end_index,:) = audio_signal(start_index:end_index,:) + drum_sounds{j};

end

end

end

% Normalize the audio signal

audio_signal = audio_signal / max(abs(audio_signal));

% Write the audio signal to a wave file

audiowrite('assign_drum_beats.wav', audio_signal, fs);

Provide those audio data, so that we can try?

Your audio_signal is an 1×n row vector but you're trying to get its start_index:end_index rows.
