WAV coded with MP3 codec

mirolm · 18th January 2001, 22:48

Hi,
I found that wav's coded with mp3 codec are played faster with mp3 plugin than wav plugin. It would be nice if
WinAmp plays that wav's with mp3 plugin, and if wav plugin is not installed WinAmp to recognize this files as mp3's.
Now WinAmp recognizes it like mp3's only if i add this files
with add file command to playlist. Add dir don't work.

What in the Wide Wide World of Sports, are you talking about?

WTF don't you rename the WAVs to MP3s????

If you don't want to do that disable the in_wave.dll (just rename the extension) and add WAV to the file associations of the MP3 input plug-in (Preferences/configure/general).

But now your normal wavs aren't played anymore...

Why would I want to rename WAV files to MP3? Your story just doesn't make any sense. You say, WAV files are played "faster", using your method. WTF do you mean faster?? A three minute WAV file plays in two minutes, if you change the extension to MP3? LOL I'm sorry, but this is one of the more bizarre ideas I've read here, unless I am just not understanding you at all. HELP.. SAWG!!!!

RIFF/WAV Encoded MP3s? (I think I got that right). Goldwave and the Fgh (one of these days I am gonna rememebr how to spell that) allow you to Encode a cross between MP3s and Wave. Maybe thats wht he is talking about?

Lets take a walk through RIFF/MP3 Land.

First off RIFF (Resource Interchange File Format) "is the tagged file structure developed for multimedia resource files." Basically it is a type of header on WAV files. Now enter MP3 files. Several programs don't support using MP3 encoding but do support all the compressions for wav that windows supports. Now, if you have the Windows MP3 decoder codec (if you have WiMP, you do) windows can play MP3 files. Bust now the fun part comes in. By taking a MP3 and putting a RIFF/WAV header file on it, you now have a MP3 that as far as any program is concerned is a wave, as long as you have that codec.

Now, on to the real question. I am assuming that WinAMP does not have all the support for all the different forms of Wave compression, so it uses the Windows codecs. Just by using WiMP you can tell that the Windows MP3 decoder is slower then WinAMP. But having WinAMP play it thinking it is a wave it passes it to Windows to decode. If you kill the in_wave.dll and get WinAMP to play the file, it is still a MP3 once you get past that pesky header, so it uses in>mp3.dll and not Windows, using its faster decoder. So playing a RIFF/WAV headed MP3 is faster (system wise) to play as an MP3 and not a WAVE file.

I am not 100% sure on this material, but it is what I patched together form reading, past experience, and common knowledge.

These wavs WILL work after renaming to MP3 (just don't try to ID3 'em). I've suggested Justin to make in_mp3 play these files, but he doesn't seem interested. When I don't have anything more important to do, I might try to hack in_mp3.dll again (I had this fix some time ago, but extra code wasn't getting loaded correctly on most computers). I need some docs about win32 executable file structure...
Another idea: get WinRipper - http://pp666.cjb.net/ripper.htm - it can extract mp3 data from these wavs and convert them to mp3 (without any quality loss, etc).
If you are familar with hex editing, you can bust the RIFF header (delete everything up to four bytes after 'data').

Sorry folks, but my english is bad.
I mean that playing wav's with wav plug-in consumes more processor time than playing it with mp3 plug-in.
