Filtering out above middle C.

    I don't know if this is possible but would anyone know how I could splice an mp3 of a piano song I have so that it would filter out any sound above a certain frequency?? i.e. that of middle C? I'm trying to figure out the bass hand in a song and can't hear it very well. I dare say this is a naive question but I thought I'd ask.

    thanks in advance,

    Many software programs offer sophisticated equalization capabilities but for what you are asking, you might hear the low notes, as low-frequency sounds but you will not hear them with their articulation clearly without their upper frequency harmonic content if it were filtered out by the use of such filters. The Analogy would be trying to listen to an orchestra with a pillow over your head. You would hear very little articulation, making that experience rather useless.

    A better recommendation would be to utilize any of the fine software programs that allow for "speed change without pitch change"? Even though there may be audible artifacts from this "effect", to be able to hear the articulation in the notes being played at a slower tempo can be very helpful.

    Well, you wouldn't really be splicing anything.

    You can do this but it may not give you the results you want. I think middle C is pitched at 256Hz. So what you need to do is run the track through an EQ and turn everthing above 256Hz down or turn everything under that up.

    The problem with this is that even though a note may be under 256Hz, the sound of the note can have elements above that frequency. Removing those elements may make it harder to hear them.

    As an alternative, look for a MIDI file or tabulature (tablature) for the song and you could get all the lefty stuff from that.

    Thanks folks

    Cheers very much folks.

    Do you know the name of any software that could be used to do this filtering?
    I don't mind that the quality of the notes won't be great, I just need to be able to get a gist even for the timing signature.

    Your Windows Media Player has a graphic EQ. Attenuate ALL freq from 500hz to get the effect you seek.
