MP32WAV?

[miskairal]

Hi all, I am after this for a friend who is trying to make smaller power
point presentations. She has been told that a programme called mp32wav
will convert and compress an MP3 file but that it is no longer freeware.
Apparently you can't use an mp3 file in a pps??

So does anyone know where to find the last freeware version of this
programme or have an old copy? She has tried several others which don't
do the job of compressing. Well they do but they lose more quality than
the files she's heard done with mp32wav. I've done heaps of searching
and came up with this link
http://esca.atomki.hu/paradise/winsite/win95/sounds.html, about 2/3 of
the way down the page but I don't know whether this is a freeware
version or not.

Also came up with this
http://www.webmasterfree.com/mp32wav.html
but am wondering if it is the right programme?

Thanks in advance

Hi!

I looked at the second link, and think that this really is the program
you are searching for.
But what confuses me a bit is that you talk about "compressing"
mp3-files which already are compressed? As to making a .wav-file out of
an mp3 effetively UN-compresses the file since .wav represents
uncompressed "CD-audio". Just wanted to make that clear

I agree. I can't understand it myself but this is what people have told
her at a pps forum. Thanks for your time. If there are no further
replies I will download it anyway and see. I'll even post back if I can
make a wav file that is equal or smaller than the mp3 )

You won't make a WAV file that is smaller than the MP3 it was created
from, but I have come across a few pieces of software that will apply a
WAV header to an MP3 file, effectively fooling the system into inserting
a file believing it to be a WAV then discovering it is an MP3 and
playing it with the appropriate codec. Used to be used for applying
compressed MP3s to AVI when VirtualDub didn't support MP3, IIRC.

Details here -

MPA2WAV is one such tool, just tested it on an MP3 here and seems to do
the trick. Command line only though dragging an MP3 directly onto the
MPA2WAV.exe works. Can't check if this works perfectly as my version of
Powerpoint (2003) seems to support MP3 directly anyway.

You don't need any special program to do that, you only need to resample
the sound file with whatever. For example...

1. MP3 @128 kbps = 3,281 KB
2. PCM wave from MP3 @ 44.1MHz, 16 bit, stereo = 36,154KB
3. PCM wave from MP3 @ 8 MHz, 8 bit, mono = 1,640KB

The resultant wave will not have the same quality sound as the wave
resulting from playing the MP3 but it is generally acceptable.

Once you have a wave from the MP3, you can resample it with Windows
Sound Recorder by loading it in same, "Save as...", "Change" (format).

You won't make a WAV file that is smaller than the MP3 it was created
from,

Sure you can...see my other response.

I should have phrased that as "You won't make a WAV file that is smaller
than the MP3 it is created from without reducing it in quality to the
point that it sounds like it's being played from a 10 year old cellphone
underwater."

The RIFF-WAV solution doesn't involve resampling and should work in a
lot of cases.

Weeeeell i could also take the mp3-file and resample it to, say 8Kbit/s
and voilá it's smaller than the WAV again, but thats not really the
point ist? : )
And, btw it's 44.1kHz not MHz (would be quite a large amount of data at
this samplingrate!)

Not if one wants a wave

Right. I'm a lousy typist

1. please shorten the quotings in your reposts as far as possible

2. please configure your newsclient. Your SIG should be "-- "
(DashDashSpace) instead of only "--". Only such way the SIG is working
for what she is mentioned - to avoid automatically the quoting due to
the right SIG-delimiter. Please see the example of my SIG and learn to
quote. THX in advance for your kind understanding.

Thanks everyone for your replies.

I used dBpoweramp to convert an mp3 to wav using 8.0MHz and 8 bit mono
(whatever that all means). The sound is not too good but the file size
is down to 1.81 MB from 3.6MB.

I have suggested to the friend that she uses something like audacity to
crop the song to just the part she needs either before or after
converting to wav. why have a 4 minute song embedded in a 2 minute pps?

I really don't see how this programme mp32wav can make the quality any
better than dBpoweramp can?

It can't. Nor can anything else.
