Sonic Differ
Highlights the Differences (Similarities) of Music Tracks | |
Somewhat similar to a Text Differ (which shows the differences and similarities of two text files), but instead of textual differences, this application analyses the tempo, frequency, key-changes and lyrics (after first using voice recognition techniques to extract them).
The output is stereo audio
of the similar pieces placed side by side.
An example is not provided (unless you ask very nicely)

is this for karaoke purposes? oh, I think I missed something here. |
|
| |
No, I was thinking more for checking your track wasn't an accidental cover of something else... Or it might be used in court copyright cases. |

([po], Check your multiply account) |
|
| |
what a cacophony! :( now you know I have no ear for this stuff. |
|
| |
Listen to it on headphones and one channel at a time (pop-in/out your headphones, if you can't cope with the binauralness of it ;) ) |
|
| |
BTW, it sounds perfectly normal to me. Actually, I quite like it. |
|
| |
it repeats - I went off to read something and yes, its growing on me - no headphones though. |
|
| |
more an automated search than a compare, yes ? |
|
| |
Yes, but that's what text differs do |
|
| |
I mean automated searching through a large database of songs, rather than one at a time (for which you can use your ears). |
|
| |
No, not a database. You provide two songs and it analyses them and plays correllated parts alongside eachother. I suppose you could run the comparison against all the music on iTunes/Amazon etc... but that may take some time. |

Please, pretty please? With marmalade on top? |

Kind of related - It's trivial to find the difference between a track and its mp3 or other lossily encoded product; it's just a straightforward subtraction of each corresponding sample value, taking into account any padding at the track's end(s). The result is essentially pure compression artifact, and is rather interesting to hear. |
|
| |
What you are trying to do sounds highly non trivial. |
|
| |
There’s actually a feature of a lot of audio editors
called “remove vocals” that uses the difference
between the left and right channels to remove
whatever is exactly in the middle (usually the
vocals). |

[mouseposture] are you on multiply.com? {social network} |
|
| |
Get a (free) account and send a PM personal message to user [dubatmultiply] {let me know your HB handle, too} and I'll let you have a listen. |
|

[spidermother], non-trivial, but non-impossible... Shazam manages to do something a little similar... and arguably, part of the task. |
|
| |
[ojsx], yes, but usually just clever mixing (subtracting the common signal - which works becauce the vocal is usually on both L/R channels). Not really the same thing, but might be part of the task, too. |
|
| |
[bigsleep], well talking Italian isn't going to help, is it?!
It could just pitch-hift/tempo-shift one track relative to the other... Non-trivial, but... somewhere I have a great link to show you... Meanwhile, skedaddle over to Multiply, let me know your Id, and listen (and retract that bone, sir!) |
|
| |
[Dub] Sure, I didn’t mean to suggest it was the same
thing; just thought it would be of interest if you
didn’t know about it. |
|
| |
I feel the need to stick the phrase "aural turpitude" somewhere. |
|
| |
Did it stay in, or has it fallen out? |
