MULTI FEATURED MUSIC PLAYER

Here we have included different effects. They are Karaoke.Surround Sound,Flanging,Reverb,Left/right Channel selection, Echo , Chorus, Bass ,Treble using 10 band EQUALISER AND IMPIMENTED IN T1 DSK 6713 .

1. ORIGINAL SONG AMPLIFIER:
In this the original song is passed through a gain block and thus amplified without any alteration.
2 KARAOKE:
This is the facility which is useful when we want to sing the song from the lyrics . whenever any audio recording is done music is recorded differently in the left and the right channel due to the available Technique known as Multitrack recording but vocals are recorded equally so that if we give 180 deg phase shift to the left and right channel and than added so that the vocals are suppressed and only the music will remain.
3 BASS :
In this the bass (low frequency e.g. Tablas, Drums etc.,) components of the audio signal while high frequency music components are significantly attenuated. For that, this we have used 10 IIR Band pass Butterworth (10 band equalizer)Filter of order 2(designed using FDA tool) which finally boost low frequency end.

4 TREBLE :
In this the treble i.e. high frequency compoments are boosted while the bass components are reduced in amplitude. For that, we have used 10 IIR Band pass Butterworth (10 band equalizer)Filter of order 2(designed using FDA tool) which finally boost high frequency end.

5 LEFT ACTIVATE:
Here from the two available channels i.e. left and right one of them LEFT is selected and by using submatrix block and other is suppressed
6 RIGHT ACTIVATE:
Here from the two available channels i.e. left and right one of them RIGHT is selected and by using submatrix block and other is suppressed
7 ECHO:
Echo is repetition of a sound by reflection of sound waves from The place which is greater then 17m away .which can be produced by using the integer delay to the same sample after the time greater than 0.1 sec(perception of human ear to store the sound heard by us)
8 CHORUS:
The chorus effect is especially easy to hear when listening to a choir or string ensemble. A choir has multiple people singing each part A string ensemble has multiple violinists and possibly multiples of other stringed instruments. When individual singers or violins play the same part, the chorus effect can be heard. Here we have implimented so as 3 different singers are singing with 3 different instruments we have done this repeating the same samples after giving the very small integer delays
9. REVERBERATION :
Reverberation effect is experienced when any signal coming from the source instead of travellin acc. To the inverse square law reflected back at the distance less than 17m and the delay time between two same sample is less than 0.1 sec(perception of the human ear)
10.SURROUND SOUND :
Surround sound effect is one in which we can hear the sound like a goodest quality.At a time one is the original song which is available in one channel and after 20 ms delay sound is available in other channel. Here we are using the principle of perception of hearing.
