Last view: 2975 days 		I'm converting MMX's Spark Mandrill music to SMW I ripped the SPC manually and want to convert it to midi using the program Midi2SPC, but it wants to know how many seconds long the song is. How can I tell the length of the SPC.

SPCs don't have any intrinsic length any more than an SNES game ROM has one. They are just state dumps of the SPC-700 sound processor, i.e. ROMs of their own - and most games' music engines happen to be written in a way that left to itself, the tracks will just keep looping.

On the idea that SPCs and such don't have an intrinsic length, I'd like to switch SNES for GBA and speak from experience: the progress bar in Sappy is not time-based, but how far along in the track data, which is why it can jump around like that. It has the same basic cause.

What Black's basically saying is that there isn't.

If it's just that, you could always write a program to do that (on a raw PCM dump, if nothing else) yourself. It's a pretty trivial problem, considering how most SPC renderers operate deterministically.

The problem is coding is my weakness.

Got a stopwatch? Or better yet, you could use Audacity (free audio editing program) to record Windows' sound output and measure it within Audacity. Trim the beginning of the recording off so you have the start of the song at the start of the track and the same for the end.

I thought of that, but I want it to loop exactly.

You can always use a bit of trial and error. It's not like it's a one-shot thing.

Last view: 3120 days 		With SPC2Midi, Let the song loop for a bit and then save it. From there open it in a midi editor. and truncate the excessive looping of it. to make it loop once. Another thing with SPC2Mid is that if the drums are set to be actual drums, Their specialized volume and controls aren't saved. So when I export a midi from SPC2Mid I make the "drums" random "instruments" and then change the instruments to proper drums while keeping the tracks separate but the channel the same. Good luck with your progress on this.

Last view: 3221 days 		Get a SPC plyer for Winamp, set it to loop once, and use the wave dump output plugin to dump it as a .wav.
Just find the length of that.

You probably used a version full of bloatware and ads, other things you can't opt out that you don't need, and full of bugs.

I suggest version 5.34:

Not unless he got it from a illegal bittorent site, it may contain a modded version if so.

Alternatively, use Foobar with an SPC plugin.

The version I'm talking about can be downloaded from winamp.com, 3.8MB extra of crap.
