HELP! Weird "Underwater" effect when reducing high and low frequency noise.

Hi everyone.
I am in a spot of bother with Soundtrack Pro. I hooked up a reel-to-reel player's audio line out to my PowerBook's line in. Then in Soundtrack Pro, I hit record.
So everything works out fine, except...
There is some hissing in the audio file which I can easily remove with the "Reduce Noise..." feature, but there is this low "rumbling" noise in the background. When I try to remove that, the entire song sounds like it was played "underwater". I tried selecting only the low noise, goin to "Process>Set Noise Print" then reducing the noise, and the underwater effect gets worse.
I need help pronto!
Thanks

Hmmm...OK. The hiss is removed, and the underwater effect is elimanated, but how do I get rid of this annoying low rumbling? I tried looking under the Analysis tab and selecting "Power Line Hum" but it couldn't find anything. High Pass Filter and Linear Phase EQ either kill the whole bass frequencies or they make the song sound "Tinny".
Any advise?
Thanks

Low sound levels in Photo Booth and Imovie

I am a new Mac user and I am trying to record a short video to email using the built-in Isight camera. I have tried to use Photo Booth and Imovie and both of them produce videos with very, very low sound levels. You can barely hear it even when turned up to the max. I have checked the Sound preferences, and it is set to the built-in microphone, about mid-level. I've tried cranking it up to the max and with and without Use ambient noise reduction checked. It has no effect. How do I get a decent sound level? It is unusable at this point. I've updated my Software and repaired permissions, and still no luck. Any help would be greatly appreciated. Thanks.

Thanks for the response. I checked my midi audio settings and they are at the suggested rate. I called up an Apple support tech, and after trying a few things he basically said the internal mics are junk and go buy an external one. In the mean time, I've cranked up the sound levels to max, so I can hear it a little, but there is a ton of background hiss. I've done a web search and several people have reported this problem. so I think it might be something besides junk mics. Why do they install them if they are completely unusable? Thanks again. I'll try trashing the sound pref's too.

Threaded alsa sound noise issues

Hello, everyone!
I'm trying to make alsa work in threaded mode, i.e. allow more than one application to produce sounds.
All I've done so far is made /etc/asound.conf
As you can see from this config I use dmix to mix different sound threads
#/etc/asound.conf start:
pcm.!default {
type plug
slave.pcm "dmixer"
pcm.dsp0 {
type plug
slave.pcm "dmixer"
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_time 0
period_size 2048
buffer_size 32768
rate 48000 #many new cards are 48000 only
bindings {
0 0
1 1
ctl.dmixer {
type hw
card 0
#end.
So I use dmixer as a default mixer. Now I can get reasonably good sound in xmms/audacious+firefox+mplayer/xine.
Without this config alsa worked only for one application at a time.
The only issue I have with alsa is sometimes noise from for example bass,i.e. low frequencies. But sometimes noise limited to very short time intervals appears out of nowhere. It's very annoying. SDL or oss don't produce such noise but they want full access to /dev/dsp and the whole point of threaded sound is violated.
Any critical input about or useful thoughts on reducing sound noise are appreciated.
ps I have old audio card CMedia with 2.1 support.

SDL will use ALSA if told - put this in ~/.bashrc
# http://www.libsdl.org/cgi/docwiki.cgi/SDL_5fenvvars
# http://www.libsdl.org/faq.php?action=listentries&category=3
export SDL_AUDIODRIVER=alsa
For the "chirping", all I can suggest is to experiment with different values for period_size and buffer_size.

X61: Now the buzzing sound/noise comes...

My X61 battery died few weeks ago after 18 months. Now comes the high pitch buzzing noise from inside. I suspect the fan, since I have not seen the HD indicator blinking. Since my warranty expired, I guess nothing Lenovo can do.

"I read on a Dutch forum the brightness control could be the reason."
No, that is another sound/noise, mutch lower more like humming.
Read from Finnish forum:

Apple service told a guy that its the powersupply. Now he's waiting for a new.
I'll report how it went, if that guy posts some results.
I noticed that the buzzing noise can be gone for several days, and then suddenly apear again.

Constant low rumbling noise on headphone out

There is a continual low distortion noise on my HP DM4 headphone out, which is very annoying when no sound is coming out, and still audible and disruptive when sound is playing. Is there something I can do about this, or is it a defect that I should get repaired? Thanks.

The problem seems better when I disable wifi. Just a muted thump every couple of seconds. It seems like the audio circuitry isn't properly shielded...

Hi saiyed adil,
Thank you for contributing to the Apple Support Communities.
It appears that your iPhone 5s sometimes produces low sound, but a restart corrects it.
It can take some time to isolate and resolve intermittent issues like this one, and I'd recommend going through the steps in this guide the next time it occurs:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

My iPod Classic is emitting a low whining noise and I can no longer access songs or audio books. Should I restore factory settings?

When I turn my iPod Classic on I hear a low whining noise coming from it.If I follow through the menus to a song or an audio book it shows the item for a few seconds then reverts to the previous menu and the whining noise is audible again. I have tried the "5 Rs" without success. Should I try restoring the factory settings - or is there something else I can do? I would be grateful for any advice!

Hi bunjamin,
just go to BlackBerry World, and update all your apps including BBM.

you can turn off the magnifying glass :

you can deactivate the "reset to Hub view" :

Iphone 4s really low sound

Hello,
From some months I experience the problem with the sound of the iPhone 4s. The sound is really low. You can only hear it if you put your ear very near to the speakers. I've tried everything. Settings -> Sounds to max. Restarting the iPhone. Once I've played Flappy Bird, the sound like fixed itself for 2-3seconds. From low sound it turned very loud but for 2-3 seconds. Then I've tried Restoring the iPhone to its factory settings - nothing again. I lost and my Flappy Bird...
So my Question is - can we fix the sound problem and return my flappy bird? I can't download it from the gamecenter.

vikAy,
Thank you for using the Apple Support Community. Due to the nature of your issue or question you may find more information by using another one of Apple's support resources - https://getsupport.apple.com/GetproductgroupList.action.

My ipod touch 4 has low sound and mostly hiss on playback.

My ipod touch's video playback (ie. taking a video and playing it back with the camera) is suddenly malfunctioning. It's almost a year old and no other issues previously. It hasn't been dropped or contaminated. I record video, and when I play back mostly what I hear is a loud hiss, and only barely audible low sounds such as talking. Any ideas? I recently updated is there any way to revert? Also after update the video and camera functioned locked up as I was trying to use them. Thanks!
Nothing is blocking my speaker, no case, and I did already try cleaning it. Audio playback is fine elsewhere.

I don't know about the timing of my issue, maybe microphone sensitivity was adjusted in the software update? However, my device was just out of warranty, so out of desparation (I use my video for baby stuff and I neeeed it , I stuck a straight pin in the mic hole and swirled around, it works just fine now. There was no visible dirt in the hole, it hadn't gotten dirty, I take good care of it, and yet something must have been in there. The mic works now after the pin fix, and I've seen several other places it has worked for others, wouldn't use this fix maybe if you're still in warranty.

Lower sound Zen Vision Plus than Zen Micro Pho

Hello! I have had Zen Micro/Zen Micro Photo in -2 years, before I this year switched to some Asono player, but the sound was low on that, and I wanted to go back to Creative for it's quality and sound.So I bought the new small Zen Vision Plus, very satisfied with video & other cool new functions! And to secure me a good sound, I bought big Creative headphones for 400 NOK, and they are very good with good sound and base(bass).But whenever I used the MP3 player, the sound dissapointed me, I also tried with the default earphones which followed, and the sound is still not as high as on Creative Zen Micro/Photo.My friend has Creative Zen Micro the old one, and we started the same song at the same time on both our players, and tried with the default headphones and the new headphones which I bought. And belei've you me the sound on his MP3 (Zen Micro) was much louder then on mine. So it is dissapointing to see that I am stuck with this MP3 with lower sound. I love the design & functions on Zen V Plus, and love the sound on Zen Micro. So I don't want to go back to Zen Micro. Is there some way to fix this? Some sort of upgrade? Or has it something to do that the MP3 in USA has lower sound and MP3 in Europe has higher, or the other way around? How do I check where my MP3 is from?I hope someone here has tips & tricks or solution to this problem, very annoying that my MP3 is "almost perfect"! I got to go play tennis now, waiting for a positi've reply, thanks a lot guys! Every single post is helpfull, thanks again!

well man all i can say is...bigger isnt always better. I have a Zen Micro Photo, its about a year old, i just have regular good ol target special headphones and its loud enough to blow an ear drum. Sometimes if i dont feel like?wearing headphones, i just turn it all the way up and set the headphones on my desk or something. sooooooooooooooooo i would just stick to the stuff you know is good...plus the micro photo is BAMF
