Auris-Filter Setup

These Scripts were made to install the libraries and apply the filters on audio successfully.

These Modules includes:

• Auris Filters

Installation:

There are two main scripts:

** Included in libav package

Make Run:

Now that everything is ready to run, go to Auris filter folder.

$ cd ~/MUSIC_DEAF/music_for_deaf/auris-filter/

Make and run:

Or, step by step. First, using Essentia:

$ make ESSENTIA or just make

Second, using PureData:

$ make PD or just make

To run the program, it is enough call the compilated object like the examples bellow:

In Essentia:

To use the low pass filter pre-defined:

./Auris_essentia 1 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav"

Ex: ./Auris_essentia 1 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav"

To use the low pass filter not pre-defined:

./Auris_essentia 2 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav" "cut frequency" "gain" 

Ex: ./Auris_essentia 2 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav" "500" "2" 

To use the high pass filter pre-defined:

./Auris_essentia 3 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav"
Ex: ./Auris_essentia 3 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav"    

To use the high pass filter not pre-defined:

./Auris_essentia 4 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav" "cut frequency" "gain" 

Ex: ./Auris_essentia 4 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav" "500" "2" 

To use the band pass filter:

./Auris_essentia 5 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav" "Cut frequency" "Band width" "gain"

Ex: ./Auris_essentia 5 "$HOME/Music/musica.wav" "$HOME/Music/MscProc.wav" "500" "125" "2"

Attention: Using Essentia you can input files of the following formats:

- WAV
- MP3
- OGG
- FLAC
- etc. In Essentia library all the formats supported by ffmpeg can be used.

In Puredata:

To use the low pass filter pre-defined:

./Auris_pd 1 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav"

Ex: ./Auris_pd 1 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav"

To use the low pass filter not pre-defined:

./Auris_pd 2 "path_to_input/name_of_music.wav" "cut frequency" "gain" "Supress value in L of gain to the frequencies higher than the are passing, use 0 if you don't want to change" "Supress value in R of gain to the frequencies higher than the are passing, use 0 if you don't want to change" "path_to_output/name_of_music.wav"

Ex: ./Auris_pd 2 "$HOME/Music/music.wav" "500" "2" "0.3" "0.4" "$HOME/Music/MscProc.wav"

To use the high pass filter pre-defined:

./Auris_pd 3 "path_to_input/name_of_music.wav" "path_to_output/name_of_music.wav"

Ex: ./Auris_pd 3 "$HOME/Music/music.wav" "$HOME/Music/MscProc.wav"

To use the high pass filter not pre-defined:

./Auris_pd 4 "path_to_input/name_of_music.wav" "cut frequency" "gain"  "Supress value in L of gain to the frequencies lower than the are passing, use 0 if you don't want to change" "Supress value in R of gain to the frequencies lower than the are passing, use 0 if you don't want to change" "path_to_input/name_of_music.wav"

Ex: ./Auris_pd 4 "$HOME/Music/musica.wav" "500" "2" "0.3" "0.4" "$HOME/Music/MscProc.wav"

To use the band pass filter:

./Auris_pd 5 "path_to_input/name_of_music.wav" "frequency of L" "frequency of R" "gain of L" "gain of R" "Q of L" "Q of R" "path_to_output/name_of_music.wav"

Ex: ./Auris_pd 5 "$HOME/Music/musica.wav" "500" "600" "2" "3" "0.4" "0.4" "$HOME/Music/MscProc.wav"

Attention: Using Pure Data only wav format file is supported.
