A question on polyphonics tones

6 replies · 1,602 views · Started 27 May 2003

Hi all,

If i m able to record a wave audio from a mp3, how do i convert the wave file to a midi file which make full use of the 24 polyphonics tone in 3650, can i use avivd program to do just that? Anyone care to explain how do i go about doing that? Thx in adv.

regards

I'm not any kind of an audio expert, but as far as I know MIDI is a digital instrument format and it would be extremely difficult or outright impossible to extract individual instrument sounds from a mixed format such as WAV or MP3 in order to convert it to a MIDI file.

With certain types of instrumental music files it should be doable to some degree, I suppose, but for all sounds (singing, talking, etc.) it wouldn't really work at all (there are no MIDI instruments that you can map the range of human speech or singing to properly, for instance).

Anyway, I'll leave it to actual experts to explain better (or refute my claims, if what I say is incorrect 😊 ).

Although there are programs that purport to convert WAV to MIDI, the result usually sounds so bad they're not worth using.

Thanks for the reply guys but that bring me to my next qns, how do i create a midi file then? if we dun convert, do u mean i have to compose?

yep, you have to compose it.
the only thing a WAV2Midi can do is create a midi file based on the pitch of the wav.... it will only be a "monotonic" tone... you can find several midi-related software on tucows, for example.

A midi file isn't really a file in the same way that an mp3 or a wav is.

A midi file is like sheet music - a set of instructions of how to play that particular tune. It contains information on what instruments should be used, what the tempo is, when to use reverb, etc.

If you play a midi file on a very basic sound card, it'll sound exactly that - very basic. This is because a basic sound card only emulates a small number of instruments.

On a more cutting edge card, like a higher end Creative Labs Soundblaster which can emulate many hundreds of instruments, the same midi file will sound much better - as often the exact instruments intended by the composer can be used, creating a richer more pleasing rendition.

So it's not as simple as just saving a recorded tune as a midi file. You'd need some midi syth software if you were to compose your own tune from scratch, something you'll find a bit of a challenge if you cant read music. 😊

Best bet is to search the web for free midi files - there are many hundreds out there and all of them will play on the 3650 or other polyphonic handset. Be warned, though, just as a poor artist can create a poor pop tune (britain, nil points!) there are some sub-standard midi files out there too, so it's good practice to look for a couple of different versions.

Best of luck 😊

I see, thanks for the info guys, so i have to know music score to compose which i absolutely have no idea.....how i wish i can make some contribution......is there some other ways i can make some quality contribution under midi section at my own site?
