problems with audio quality

[rajij]

hi all, first timer here.
I've created a video compilation of clips for a friend, but some of the clips have ended up with really prominent hiss on the "s"'s in the dialogue, I've tried everything I can in Premiere and Ulead vid studio to no avail, any ideas would really be appreciated. I have the output in both AVI and Mpeg format and intend to create a autoplaying "business card" using freeloader.
hope that's all clear.
cheers in advance.

Not Sure! But you could try the following.

Demultiplex your AVI. Use virtualdub( www.virtualdub.org ) and open your AVI. Click File -> Save WAV.
Open your WAVE file in any Sound Editor ( Nero Wave Editor, Gold Wave)
and apply the Equalizer function to cut out the High Frequency a bit. With a little trial and error it might work.
Save your converted Wave file and multiplex your Video and WAVE file. Use VirtualDub and with the video loaded, click Audio -> WAV audio and select the WAVE file. Click on File -> SAve AVI.

hey, thanx for that, once I've got a sound editor I'll give it a go. I did try using the equaliser filter within premiwere, but it didn't really do much!! Thanx again.

here's an update,
I've tried dineshs' plan, but it didn't produce the right results!! Any more kindly helpers out there? please?
cheers in advance,

did you load the "AVI" into www.goldwave.com

fix the problem and save as WAV

[rajij]

erm, yes I've opened it into goldwave and tried moving the graphic aqualiser sliders up / down on all the various frequencies, but it doesn't seen to be making the right difference! It could be that I'm just not doing it right - unless there's any other ideas I'll keep trying!!

Thanx for advice anyhoo!

open the file in Soundforge5 then just select the places (one by one) where the "hiss" is proeminent, then you'll have many options......
Get the waves restauration plug-in and you'll have X-noise etc....

A monk's work but when you like editing.....

"OO"

ps: and say to the boom and sound guys to make a better job next time or they are out of job....)

[rajij]

heyy - is that oo?

thanx for advice, i don't think the problem stems from the original filming, the hiss isn't prominent on the VHS's I've captured from. as this has already taken so long, I'm gonna re-capture all the clips and re-edit! More work - not doing this for a 'nominal fee' again!!
cheers anyway,
raji

[rajij]

ooh, actually, while I'm here, does anyone know of a better software to use to get the mpeg to autorun once it's burnt onto a cdr? I'm currently using freeloader, but it's a bit hit and miss!

thanx again,
raji

One reason why this may be occuring is because you had increased the sound level too high while capturing,resulting in distortion in the high frequency areas. Try reducing the LINE IN Record volume, or your source volume if possible. As a result ,if the sound you capture is too inaudible, you can still use the sound editor to normalize (or) maximise the volume subsequently.

cheers dinesh, I'm doing it today, so I'll definately watch that, can't afford to f*** it up again!
