Wav Audio filter in C

Description

This is simple wav audio filter. I coded it as a College project.

modes:

info

The program has a function to get information about the wav audio.

$ wavinfo -i input

filter

The Filter has 7 different filter modes:

1. volumn adjust:

It allows volumn adjustment of your wavfile based on a V (0.0 ≤ V ≤ 10.0, default: 1.0). It basically multiplies the samples by each sample value.

$ wavvol -l V -i input -o output

2. normalization:

This filter makes the audio normalization, that is, the automatic volume adjustment.

$ wavnorm -i input -o output

3. reverse:

Is outputs and reversed audio

$ wavrev -i input -o output

4. echo:

This filter outputs an echoed audio

$ wavecho -t delay -l level -i input -o output

5. extended stereo:

The Extended Stereo Filter allows you to increase channel separation in a stereo signal.

$ wavwide -l k -i input -o output

6. concatenation:

The concatenation filter receives as input one or more audio files and generates an output containing the concatenation of inputs in the indicated sequence.

wavcat file1.wav file2.wav file3.wav ... -o output

7. mix:

it mixes one or more wav files

wavmix file1.wav file2.wav file3.wav ... -o output

executing the audio-filter

There is a makefile with the arguments to each function avaiable in the filter. Here's a example:

make wavemix

Then, an executable file "wavemix" will be created in the current folder. So, just execute the file with its respectives arguments:

./wavemix file1.wav file2.wav ... -o output

There's a makefile option to generate all the executable files:

make all
