uFmod + Freebasic

[ninogenio]

ahh cheers jim i thought it might be something along those lines.

any idea if ufmod can return the audio data at whatever position the buffer is at? if not would it be a possibility to add such a feature?

[Shockwave]

This calls for some Karma for Nino and Jim, that's a feature I didn't realise was there!

If the frequency of a channel can be returned, a spectrum analyzer could be made.

[ninogenio]

cheers shockwave yeah stuff like media player effects can be acheived through pitches and drops in the l/r channel volums.

it works pretty much the same as the bass.dll.

To get the frequency graph, you need to keep a track of the amplitude (volume) against time and use what's called an FFT (or DFT) to get the instantaneous frequency.  Frequency is defined as rate of change of amplitude vs. time.

Either you want to poll that call to get the volumes really fast (simple, but cpu intensive), or you need to get a pointer to the audio buffer (a few ms worth) when it gets delivered by the driver to the sound card (needs a change to ufmod I think - need to research that).

i can see that keeping track of time would be quite easy but returning a pointer would be handy aslo. anywho cheers jim.

Hello guys . . .
Im using FMod at the mo but it won't play protracker mods . . . and I have loads of tunes (other peoples!) i want to use!!!! Does UFMod play other types of mods?
I love FMod cos I have now written an equaliser around it . . . I don't really want to have to start again with new code for UFMod do i? has anybody found a way around getting an equaliser to work?

You could load your protracker song into a modern tracker and then save it as an XM to make it work.

I like Ufmod because it's so tiny, I haven't made an equaliser with it yet though, I don't know about anyone else...

[DrewPee]

slightly off topic . . . has anybody found a modern tracker program that actually works like the octamed or something like that works with vista?

I don't have Vista here, but you can try Milkytracker or Madtracker, you can use both to load a .mod file and save to .xm file.

Slightly offtopic, sorry.

I am fairly certain that the BASS library plays those mod files. But unfortunately I do not know how to use that with FreeBasic, perhaps someone else does..

In the new version of Freebasic it comes up with

Are you sure you included windows.bi before mmsystem.bi?
