IMac PPC :: Choosing Bit Depth While Recording Audio?

Apr 5, 2012

Do you know of any simple audio recording app (ie: not a monster audio suite) which takes low CPU usage, and lets you choose the internal bit depth using for audio sampling (ie: sample at PCM16, at PCM24,...)  ?  

Now, in case you need it, the long version of the question: 

I'm digitizing my huge collection of audio tapes, with my G5 iMac (OSX 10.4). The quality of the recordings is somewhat low, so I don't need a high-end audio card, and I believe the builtin audio card of this G5 is more than adequate for this task (Burr Brown PCM3052 with support for PCM16, PCM24, and AC3 16). 

I've done my first tests with the just-released new version of Audacity (2.0.0), which is compatible with 10.4 and higher, so I'm very happy to be able to install a brand-new application in 10.4. 

Audacity works fine, but has a couple of issues: 

First, you can choose the audio track bit depth, but not the internal bit depth at which you're sampling. In other words, I'd expect to use some selector to choose from PCM16 or PCM24 recording, which is what this iMac seems to support. However, I can only choose the storage bit depth, not the sampling bit depth. I suppose Audacity is recording at PCM24, but I've no way to test this. 

Second, it takes about 40% CPU usage while recording (yes, I disabled the realtime graphics update of Audacity... if I don't disable it, usage becomes 60% or higher). 

I tried Audio Hijack Pro (well, the last version supporting 10.4), and it won't let me choose the sampling depth either.

IMac :: ISight Audio Recording Only Through One Speaker

Jul 8, 2010

I am running leopard on an iMac 24" and am having trouble getting my iSight camera to record audio on 2 channels. I have changed my audio input to line in (inbuilt input) in order to record using a better microphone than the inbuilt one in my iMac, and am running a Shure microphone into the input in the back of my iMac via XLR to 1/4" stereo jack cable and then through a 1/4" to 1/8" stereo jack adapter. However when recording video in Photo Booth, iMovie etc. the audio only plays back out of the left speaker. It is not a problem with the output because all of my other sounds (music from itunes for example) play fine out of both left and right speakers. I believe I have run everything into the computer just fine and I can get 2 channels when recording like this in Garageband and Logic.

IMac :: Depth Of 27" IMac On Your Desk?

Oct 23, 2009

According to the specs on the Apple site, the depth of the iMac 27" is 8.15 inches (20.7 cm). I assume this is including the foot? Could someone measure the total depth of the 27", from the front to the back including the foot? So the full depth, just to be sure?

My desk (Ikea Galant) has a depth of 31.5 inches (80 cm), so it's not that deep, and it's setup against a wall. I'd like to know how this monster iMac would look on it, and if my face isn't going to be too close to the screen (now about 25 to 30 inches).

OS X :: Recording Audio On Mac - No Sound

Apr 5, 2010

I tried to record some audio (voice) with garageband earlier this day and it didn't work! I have a built in microphone that is working fine, it tested it (mac OS X, version 10.5.8) and my input volume level is turned up (system preferences). I tried to record with isight (imovie) and can record a video, but no sound eighter. I've been able to record in the past with garageband so i haven't a single clue what happened.

MacBook Pro :: Make Hum Softer While Audio Recording?

Jul 13, 2010

My macbook pro runs louder than my now dead powerbook G4 used to. I'm wondering if there is a way to make the hum softer when I'm doing audio recording? I know it's bad to put something cushy underneath since it will heat up the machine, but I've experimented with that kind of thing, and it does lessen the hum. Are there different feet I can attach? I've searched the forums and I'm surprised other people haven't written about this.

Intel Mac :: Crackling When Recording Or Playing Audio

Mar 14, 2012

I'm having a very annoying problem, and I simply can't figure it out. Recently I updated my OS from Leopard to Snow Leopard, because I had some problems with the firewire connection to my fireface 400 sound card. So far this seems to have solved the problem, and for a couple of weeks I was actually able to get some work done. Now a new problem has occured: 

When I input audio (i.e. trying to record something) I get some really weird crackling noises. It's very different how loud they are. Mostly they are at the same volume as the instrument I'm recording, and normally it sounds very digital. I've tried hooking a presonus firebox up to my mac, which gave me the exact same problems, so it can't be the fireface that's the problem. The problem is not something that occurs, when recording, but simply when sending audio into the mac. There are absolutely no problems when playing back files from iTunes and Logic.  

I've tried repairing disk permissions, and ran all the  tests in techtool pro, which all turned out fine, so I'm having a hard time believing that it's a hardware issue even though I've had problems with the firewire connection earlier.  
Though it does not sound like clipping, the problem seems to  occur more rarely, when playing soft, which just makes it even more weird. 

Model Name:iMac  Model Identifier:iMac9,1  Processor Name:Intel Core 2 Duo  Processor Speed:2,66 GHz  Number Of Processors:1  Total Number Of Cores:2  L2 Cache:6 MB  Memory:4 GB  Bus Speed:1,07 GHz  Boot ROM Version:IM91.008D.B08  SMC Version (system):1.45f0 

Everything is up to date, it just seems like something has been messed up somewhere inside the mac. Next step is to wipe the hard disc, but I'd rather not do that.

iMac, Mac OS X (10.6.8)

MacBook Pro :: QuickTime - Bad Recording Audio Quality

Jun 25, 2014

I am using QuickTime to record audios of myself talking in a quiet room, using the built-in microphone, but I just found that the audio quality is poor, even less than the voice memos I recorded on my iPod touch 4 (I said the same thing in the same room). Although I can hear my every words, I think it is near the sound quality of talking on telephone; the voice is not clear and pure.

I have the model of early 2011 MacBook Pro, with the newest OS X Mountain Lion.

But I'd like to have it on my Mac Air notebook so I can have it with me when I travel. 

However, when I click on the "address" to download it takes me to a dropbox sign-up page.  I'd rather not sign up with dropbox.

Software :: Video Recording - Audio With Cricket Like Sound In Background

Nov 17, 2008

I use my quicktime and built-in isight on my macbook to make video chats and email them to my relatives. The audio in my recording hace a "cricket like sound" in the backround. This does not appear when I just do an audio recording. Only when I do a video recording. I use the built in microphone. I've adjusted the microphone settings in the system preferences still with the same result.

When accessing the website; 'WhatUsersDo', which is used for testing websites, you are required to provide an audio recording of your thoughts about the website which you are testing, However, I am unable to submit an application to become one of the testers, as it is saying that I need to enable a microphone before I can continue with my application (as you are required to take a practice test during the application).  

I have looked through other forums, and my microphone is working fine.

Intel Mac :: Choosing A SSD For My IMac 27" Mid-2010

Jul 4, 2012

I don't really know which one to choose actually. First of all, does my iMac supports SATA III? If not, maybe i'll buy a new iMac.If it supports SATA III then i found the Corsair Force 3 480GB 2.5" SATA III SSD for a reasonable price. Do you recommend that? Does all the SSDs on the market work with mac without problem? I also want to upgrade my 4GB of 1333MHz memory to 8 or 16. There are 2 empty slots right now. Can you please make a recommendation about it too.

OS X V10.7 Lion :: Reduced The Screen Bit Depth?

May 8, 2012

When I was on Snow Leopard I was painting in Photoshop in 16-bit mode on my 21" Wacom Cintiq.It was a fantastic experience to finally have true control in settle changes in hues and shades all over the spectre.

Now that I've updated to Lion, the screen doesn't display true 16-bit graphics anymore, but instead there is pretty noticable banding. A sort of real-time downsampling in bit-depth going on. Even flickering on some grey hues. I'm very sad about this, and it's affecting my work.

I have a hunch Lion is harder on old graphics cards than Snow Leopard was.

Is my machine too old for displaying true 16-bit/ 32-bit graphics with Lion?

In the system info under the graphics card it says: 32-bits color (ARGB8888), but it clearly isn't the case in terms of what is sent to the display. 

MacBook Pro, late 2009, 8GB ram, 2,66 GHz Intel Core 2 Duo, Unibody

NVIDIA GeForce 9600M GT 256 MB 

What I've tried so far (without solving the problem)

Closing Macbook screen to run only one display (Cintiq) (to save graphics memory, I thought) - no change.

Trieid displaying the same 16-bit image in different apps: Photoshop, Preview, Quicklook, Pages - no change

Forced monitor into "billions of colors" using SwitchResX - no real change 

Anyone who knows more about this? 

I will now try:

- finding Cintiq driver updates

OS X :: Choosing Between Updating My Macbook+iMac Combo OR New Macbook Pro?

Nov 6, 2010

I currently have a Macbook running OS X 10.4.11 -- I know, I'm really behind.

It's specs are: 2Ghz Intel core duo, 1 GB ram, and 80 GB hardrive. It's a mid 2007 model. It's now slow and the hardrive is almost full. If I want to continue using it--I definitely need to update my OS, new RAM.

I've been thinking about the iMac I'd probably choose to have 2TB option for the hardrive and giant screen, and use my Macbook for it's portability, basic word documents, internet browsing etc.

With all my current gadgets, I will have used up over 216 GB just starting off. (currently I'm not really able to optimally use them to capacity because my hardrive is too small.

IMac :: Which Model Suits For Recording (Music) Purpose

Mar 4, 2009

I've been looking at buying a Mac for some time now and recently decided the iMac was the way to go. Now I'm not sure whether the new model suits my needs better than the old, so I was wondering if somebody could give me some advice on this.

What I'm going to do with it:
- record audio with an external audio interface
- use Cubase or Logic
- use an external full-hd monitor (dvi and hdmi inputs)
- use an external FW800 harddisk
- playing or editing hd-video (editing is not important, but it would be nice)

Does DDR3 and higher memory bandwidth give me any advantage? I think recording audio isn't that hard on the memory, besides using samples (which I won't besides some drum-sampling instrument like ezdrummer or addictive drums). Does the shared video memory affect overall performance? Or is it just like having less RAM? I know the old model has an FW400 and a FW800 port, but are they on the same bus? I heard someone say something like that, which would mean that my external harddisk would run on 400 when I connect a FW400 interface to the 400 port. I tried my best to read as much as I could about Macs and specs over the past few months, but I feel like I know too little about above mentioned issues to decide on the new versus the old iMac.

OS X :: Advice On Choosing The Right Mac For University?

I'm hoping that I'll get into Bangor University in September in Wales and I really want to switch to Mac before going there! Anyway, I need a Mac that will be powerful enough to run multiple sessions on photoshop, a word processor and the internet obviously at the same time! So the one I'm planning to buy at the moment is the Mac Mini, and I was wondering if I would be able to run it using my Windows laptop by using the display, keyboard, speakers and touchpad on it. Does anyone know if that would be possible? Because I can't be bothered buying another keyboard and display!
