27kb wav will not convert properly

[frew]

Hello,

I have a small wav file that will not convert from

PCM,22,050 Hz, 8 Bit, Mono

to

PCM,44,100 Hz, 16 Bit, Mono

using DMC

If anybody would like to try to convert this (Bill or Christina perhaps?) please let me know.

It might be the same old problem of the filesize being too small for DMC to properly deal with it.

I do wonder though, why is DMC not able to deal properly with smaller files, since they are so common...nothing really unusual about them. I don't want to buy DMC because of this recurring inability of DMC to propely handle these smaller files.

Thank you,

frew

Hi, you can send it to me if you like. You still have my email?

Re: 27kb wav will not convert properly

I just recorded a short wave file at 22100Hz, 8bit, mono and then sliced off the first 27KB. This 27KB file, in that format, is 1.27 seconds in length! Anyway, I tried converting it using DMC to 44100, 16 bit, stero and it converted just fine in less than 1 second. I realise that does not solve your problem but your short file SHOULD convert.

Thank you for your replies.

Christina, I do not have your email. I think you got the files I sent before from Bill...because I had sent my other problem files to Bill.

I'd like to send you and adaywayne my current problem file to see what you can do with it?

Thank you,

Ok, check your PM's.

Re: 27kb wav will not convert properly

Frew, I got the file converted in 2 steps. It doesn't work in one step alone, it results in a sped up file.

I emailed it to you.

The steps starting with file0.wav (8-bit, 22KHz,mono to 16-bit, 44.1KHz, 2-stereo):

1) 16-bit, freq-as-source (i.e.keep the same 22KHz), 2-stereo - result: file1.wav
2) bits-as-source (i.e. 16-bit), 44.1KHz, channels-as-source (i.e. 2-stereo) - result: file2.wav.

Audio-wise, to me, the result sounds the same and it's satisfactory. I haven't checked the wave pattern yet, will do soon and post the findings.

Incidentally the trouble spot is in going from 22KHz to 44.1KHz when also starting from 8-bits, regardless of whether 16-bits, 2-stereo are or are not selected as well.

It looks as if 44.1KHz really has to be the last conversion, to be applied to a 16-bit file only. The stereo part doesn't matter, that just doubles the tracks.

Frew, I didn't even know there was a private messages feature in this forum!! I'll check it out and let you know whether I get the same results as Lady Christina.

Frew, I checked, but there is no private message for me from you.

Re: 27kb wav will not convert properly

Frew, I also used another program I have, Record Producer Deluxe, and was able to convert it in one step to 16-bit, 44.1KHz stereo.

This program however only works on one program at a time. And even if I say it's in one step, it's really a few actions I have to do while in the same program. In the end it's faster to do 2 conversions to wav using dMC than one using RP.

Re: 27kb wav will not convert properly

adaywayne, sorry I had to take off for a while before I got your message that you may have wanted the file...


Christina, yes thank you very much for your good work.
It does appear that using the first conversion to change only the bit from 8 to 16 is the key. Then in the second conversion go for changing the sampling rate from 22khz to 44 khz.

Nice, Now I'll be probably do my batch conversions where I change just the bit rate as the first step. Then for the second step I'll change the sampling rate. (I think that's what it's called...44,100hz is the sampling rate right?)

Thank you very much for your help,

You're welcome.

Just make sure than when you set the frequency to 44.1KHz ( http://www.audiovideo101.com/diction...pling-rate.asp ), the bits are already at 16. Mono or stereo doesn't matter whether it's set in first or second step.

Re: 27kb wav will not convert properly

I will note it as a bug.

I will note it as a bug.

But it worked perfectly in a single step for Me!

Oh? It did? Did you listen to the before and after?

Re: 27kb wav will not convert properly

As I said, Christina, I didn't have a copy of the actual 27KB file in question, so I recorded a 27KB, 8-bit, 22050, mono file myself and then used DMC to convert it to 16-bit, 44100, stereo in one step with no problem. That suggests perhaps there was something non-standard about the "problem" file.
