Clean up audio

Anybody have a suggestion on how to clean up audio in a video without having to re-import the files into iMovie?
Thanks!

Thanks for the suggestion -- I also have the Toast Titanium Pro bundle, and didn't realize that I already had the SoundSoap program (SE 2.2.0 version). However -- how do I get the audio file out of iMovie into SoundSoap, and then back into iMovie after cleaning? After splitting the clip (isolating the 2 min portion with the troublesome audio) in iMovie, I did Edit > Detach Audio, but can't seem to copy the audio file into SoundSoap.

Cleaning up audio causes "wind tunnel" effect - how to fix?

I typically use Soundbooth to clean up any problems in audio, like hiss or buzz/hum noise. I just use the default "Clean Up Audio" tool on the left side when I open the program. It seems, though, when I adjust the levels to anything decent to get the problems out of the audio, inevitably I get a sort of "wind tunnel" effect in the sound. Does anyone know how I can prevent this in the future?

Cleaning up audio (wind, camera noise)?

I made two mistakes in filming my recent movie:
1) I forgot to turn on the wind shield on my camera for a couple of the outdoor scenes, which resulted in a low rumbling of wind that tends to overshadow the dialogue, and
2) My camera's microphone is located at the bottom front, and in the first few days of filming when I gripped the camera body, a finger or two was covering the mic. The result was a tinny sound (probably the camera motor) that tends to mute the dialogue.
I was wondering what I can do to try to clean these things up. In the past, I've used Audacity to clean up audio, but I wanted to know if other solutions exist. Thanks.

Hi Jim - it's me again!
You might like to have a look at SoundSoap (but it's not free). I've heard good reports about it. Although, apparently when removing background sounds (such as wind) other sounds (like voices) can sometimes be distorted or muffled by the process. This applies to most products like this. So things may end up sounding worse. It's probably a matter of trial and error.

Software for cleaning-up audio

Can anyone suggest software good at cleaning up audio? I am trying to preserve some audio tapes and am finding two major issues: tape hiss and occasionally high-pitched whistling sounds. Anything out there that can help clean these up? I realize tape hiss can't be cleaned up all that much without seriously compromising the original sound. But I'm hoping there's a way to isolate the frequency of the whistle and remove it. Any suggestions? Any shareware perhaps??
Thanks!

Dimitry,
Check out this site: http://audacity.sourceforge.net/ I wanted something to do just what you're hoping to accomplish. I too have a lot of tapes that I'd like to convert to CD; after doing one conversion(to date), though the exercise was worth the learning experience, I may not continue and simply make new CDs of music that I have on my LPs. One of the plug-ins is tape hiss removal. It probably will remove the hiss quite effectively. It's an open source program so no cost is required.
Hope this helps,

Help me clean this audio, please.

Hello everyone.
I need advice from anyone who is willing to help. I have some video footage for which I'm trying to clean up the audio. I'm hoping to get rid of the noise and also EQ or anything else to get the audio sounding as good as possible.
I am willing to use Logic or Soundtrack Pro for this, as I have both.
The source material was recorded with a camcorder microphone, so I'm sure it will never be miraculous, but I'm hoping you can all give me some tips about how you would go about getting this audio sounding better. It's a videotape of a musical called "Once On This Island".
Here is an mp3 file with two excerpts from the show. The first part is a large ensemble number, and the second part is a quieter section with some dialogue and some solo singing. This way you can hear the range of what is in the audio.

Please download the file and listen, then give me advice on the best way to clean it up.
Thanks in advance!

Download the demo of iZotope RX-it will denoise your material very good and very fast.

You can use the demo for some days and it's fully functional. Use it in standalone mode or in realtime as a AU-Plug In.

Cleaning up audio files with the eax clean

hi gang]
i was recording 78 records before and i was useing the eax clean up to clean them up.after i use the clean up im not sure that clean up did anything.it doesnt save the new clean up as a new file.how do i
no if it cleaned anything?also it says you have to use it with the creative media organizer-how do i do
that?is there a procedure?thanks
coonsanders

Creative MediaSource can realtime clean up your noisy audio. So, you can connect your records into the line-in of your sound card and then enable MediaSource to do a li've clean up of the line-in.
If your have noisy audio files, you can also use MediaSource to do a li've clean up of the noisy audio files as the files are played via MediaSource.
However, MediaSource does not save the "cleaned" audio. One trick to use What U Hear recording to record the cleaned audio.

Suggestions for Cleaning up Audio in this clip

http://www.youtube.com/watch?v=A7IXq1QDYaU&feature=youtu.be
Hello Creative Minds,
I'm working a remote editing gig for a fellow wanting to create a video lecture series. In this clip, I sampled out the noisy and distracting Background ambience of the room he's in. Unfortunately, now this man sounds like he's talking thru an underground speaker from across the playground...
Audio's not my forte in FC Studio. Any suggestions to correct this clip's audio track?
Thanks a million, folks!

Often the very noise you wish to remove is directly in the frequencies of human voice. The more you remove the noise, the more you screw up the voice.
Play with specific frequency dampening, but if it is general "white noise", you just supress it some and live with the result.
Also, sometimes a noise gate can deal with really low level noise.

fwiw- for the next series of lectures, get him to invest in good microphones and have them well placed in the room.
I often record talks in a room where the a/c noise is distracting. By good placement of mics I can reduce that crud to well below the irritation threashold...

Can FCE 'clean up' audio & dv or dvpro

Hi,
I'm working with a clip recorded on a Sony PD150 with the onboard mic. Audio is pretty good, but to my ear it does seem like I can hear the camera slightly. Does FCE have a way to improve this? I've been tinkering with audio filters, but I'm not really making any progress.
Also, the pd150 can record in dv or dvcam. Is one preferable to another from the FCE perspective?
Thanks,
Tom

Hi(Bonjour)!
For the audio issue, try 10 or 30 band graphic equalizer to isolate the motor frequency.
DV suported by FCE on FCE spec web page:
Plug-and-play support for most DV25-format camcorders and decks: MiniDV and DVCAM (NTSC or PAL)

I have a silica gel ball inside my 35mm audio port, how can i fix it? Can you clean te audio port from inside?

I have a problem; a silica gel ball is inside my 35 mm out, was a problem with a silica gel bag that was in my backpack.
I tried a lot of things but that ball still inside, there is a way to clean the port from "inside"???

from the inside, no.
jewelers 'fix' such issues as broken off mic jacks and stuff like this all the time
contact a jewelry repair place, likely charge you $20 if you cant end up getting it out
next time use a case for your Air in your backpack

Clean up audio quality

I have an mp3 file that is poor quality because it came from a tape. Does anyone know a program taht would get rid of hiss and slight background noise?

Amadeus Pro, SpinDoctor (used to be part of Toast), possibly something in Audacity (free). You can spend anything from a few dollars to hundreds of dollars for high-end. I remember that Amadeus let you sample a section for typical noise, then apply the filter to the whole file.

My Read Aloud ePub producing popping sounds despite clean audio, any suggestions?

Hello Experts,
I'm having trouble with my Read Aloud ePub, when loaded to iPad and run through iBook, some of the pages produce pop sounds before the narration starts. I have separate audio for each page and they are clean. Audio don't have any popping or clipping sounds in it but when run in iPad it produce pop sounds.
Any suggestions?

Globally Replacing a Noisy Media File with a Cleaned Up File in FCE

I'm working on a project where I have found that one of my master clips has an audio issue. I've used subclips from this master clip in many places in my video. I'd like to know if thee is a way to process the audio of this master clip and have FCE pickup the cleaned up version of the media automatically for all the subclips used in my sequence. I've found a noise removal effect in a program called Audacity that works quite well to get rid of the noise in my master clip. I'm just not sure about the workflow to get the cleaned up file back into my FCE timeline. Audacity is supposed to work as an external editor in FCE, but haven't been able to get this to work correctly. Here's my proposal:
1. Place my master clip on new sequence and export the audo tracks to an AIFF file.
2. Process this file in Audacity using the Audacity Noise Removal effect and save to a .AIFF file.
3. Import this clean .AIFF file back into FCE.
4. Repace the audio on the timeline with the cleaned up audio file.
5. Export this sequence to QTMovie.
6. Exit FCE and using Finder, replce the original master clip media file in the Capture Scratch directory with the new file with the identical name as the original file
7. Re launch FCE and hope the program picks up the new file like nothing had changed.
Does anyone know if this can work as a way to do a global replace on a mdeia file tht needed cleaning up.
Doug

Should work as long as both files are the exact same length - the alternative is moving your original file to a new location then using the reconnect menu to navigate to the edited clip.

Audio runs slow!

Hi i just installed a new board, and updated existing OS with drivers, and now the audio runs at what sounds like half speed. Is there a bios setting I need to tweak, or am I going to have to reinstall the Hard Drive?
Intel P4 3.06 533 MHz processor onboard. No overclocking required.
Terratec 24/96 cards x 2 installed
1 x Audigy platinum installed.
I am recording audio with a band, and this setup was fine with two other boards now I a m stuck, I cannot make much sense of the bios, but it maybe I just have to reinstall
Any help appreciated

If the mobo has onboard audio go into the bios make sure its disabled.
other than that there is nothing in your bios or motherboard that can cause this or fix it. contact Creative.
open AudioHQ there is a setting there for 48/96khz audio, change it see if it changes.
also in the eax console or the speaker settings console there is a setting for changing the way the music is played,, like clean up audio or time shifting, make sure is set properly.
and is a Terratec 24/96 cards x 2 installed
sounds to me like thats the cause ... maybe
is it some sort of audio device ?
if so your problem isnt the mobo, its the audigy card not working with whatever that is

Audio clips too quiet at max volume

After putting audio from STP into an FCP project, some friends and I turned the volume all the way up in the audio editor window. Even after doing that, however, it's still way too quiet. Is there any other way to raise the volume so that the audio is loud enough?
iBook G4 Mac OS X (10.4.7) 1.42 GHz Power PC G4 1GB DDR SDRAM

I have never liked that "duplicate the track" to make it louder method. When you duplicate the track, you're also duplicating the noise floor, making the background noise twice as loud, too.
If you've got the audio track open in Soundtrack Pro, use the compression plugin, or dynamics, or whatever they call it in Soundtrack (I use Cubase). Use that to bring the level up. What you'll also get with the compression plugins (not the same as video compression, don't worry about that) is it will bring the low level audio up and the high level audio down to even it out. It won't raise the noise floor as much because when audio drops below a certain level (set this right ABOVE your noise floor/room noise) it stops raising the low level audio. That way you have a more even level throughout the track. How does the mix of the announcers on the NFL on FOX always sound so good when it's live? Compression. Keep your levels in check.
So use the compression plugins to even out your sound, maxing out at about -1db. Export it.
Now, import that track into FCP and bring the level DOWN to -12ish.
Much cleaner and audio way of raising levels. Duplicating the clip to make it louder is not the way an audio facility would do it. It's a quick video guy way of doing it. It does the job, but not well.

Audio Distortion on FW400 Audio Interface Daisy Chained to FW800 Hard Drive

Hi everyone! I’m an experienced Mac user in need of help resolving FireWire device issues.
I received my 27” i7 iMac a couple of weeks ago running 10.6.2. After a long process of migrating over from my 9+ year old Dual 500 MHz G4 PowerMac tower, I was excited to set up two 1TB drives inside an OWC Mercury Elite Quad-Interface Dual HD enclosure via FW800. I then daisy chained my Focusrite Saffire 10 audio interface (FW400) to the HD enclosure via a FW800 to FW400 converter cable. To reiterate:
i7 iMac (FW800 port) --> OWC Mercury Pro Quad-Interface Dual HD Case with 2X 1TB drives (FW800) --> Focusrite Saffire 10 audio interface (FW400)
Although a lot of people may disagree, I wasn’t concerned about having my FW800 hard drives drop down to FW400 speeds because of the slower audio interface. I have read enough about the 1394 FW protocol and its ability to use something called beta clouds, allowing both FW400 and FW800 daisy chained devices to operate at their maximum speeds. So far, so good. The drives are reading/writing data fast.
As many studio audiophiles have said, you should separate your audio recordings and projects from your startup disk. I’ve done so. However, call me naïve, but I did not imagine that every time my external drives read or wrote data, my audio interface would go into a state of distortion (like raising the gain on a track as high as it can go). When the activity of the disk drops below a certain level, the audio interface usually switches back to clean pristine audio. I am experiencing this within a studio environment and with simple CoreAudio iTunes playback via my audio interface. How is this possible? Am I doing something wrong or is there a blatant limitation with the FW chipset Apple is using for their single bus in the new iMacs? If anyone can provide me with a solution or a convenient work around, I will be very grateful!

Thank you for the feedback, Rick. To shed some light on daisy chaining FW800 with FW400 devices, I provide the following quote from one FireWire technical article I came across on the web:
+"The concept of beta clouds allows FireWire to keep all devices on the bus to operating at their maximum speeds. Devices are cluster together on a logical level in a cloud. The cloud operates as a single block at 800 Mb/sec. The borders of these clouds are where legacy devices are connected, operating normally. Each device operates at its highest speed."+
In short, beta clouds allow both devices to operate at their highest speeds.
Both the audio interface and the external hard drive enclosure has its own, connected power source.
I wish I had the option to use USB2 with my audio interface, but it only has a FW400 connection.
