Lead Instrument Removal
The lead instrument can be vocals or a solo. Backtrackit applies phase cancelation method to reduce whatever is in the lead and center of the mix. This highly depends on the mix of the song and the quality of its audio. It works best on songs where the vocals is centered in the mix and the file is not a low quality mp3. You can quickly reduce the lead instrument to practice guitar solos or sing along!
Clicking on the "KEY" button allows you to shift the key of the song up or down. This is useful when you're a singer and want to shift the song's key to match your vocal's perfect pitch. If you're a guitarist or a bassist, you can quickly shift songs that require changing your instrument's tuning. Songs in D# can be easily played in standard tuning by shifting the key to E.
Clicking on the "BPM" button allows you to speed up or slow down the song's tempo. Shredding solos can be slowdowned so you can learn and practice them! If you're a drummer, you can practice your setlist with a faster tempo!
Guitar & Piano
This gives you a quick access to see guitar or piano scales and chords while jamming. There are 16 scales and more than 140 chords! If you're playing one of Backtrackit's backing tracks, clicking on the guitar/piano buttons shows the track's chord progression!
You can set the start and end of the passage that you want to loop. Jam over a specific passage or practice playing it easily without interruption!
The EQ button allows you to set and adjust the frequencies such as bass, middle, treble of the audio. If your speaker or headphone do not a flat output, you can change the EQ to have a better audio quality. If you're a bassist, lower the bass frequencies while playing your favorite songs.
You can save the song with new modification that you made. The changes can be: different key or tempo, muted leading instrument, or new EQ! The output file is a WAV file stored in your phone under "Backtrackit" folder.
