"bare bones"computer

08/27/2008 10:09 AM

I will be purchasing some software that is used in "cleaning up" audio signal. I need a stripped down "bare bones" computer that will run software like CLEAR VOICE DENOISER or GOLDWAVE . I dont need a $1000.00 computer! Any suggestions? I would like a laptop. James

To each his own but I could never suggest a pawn shop for any sort of computer purchase. Call me old fashioned(?) but you should be able to get a budget laptop from any of the major PC vendors. I would check out Asus or Acer. (check out the Asus EEE PC)

Also there are specialty shops who will build a computer to your specs while keeping a very reasonable price. Here is a link to the place where I ordered my most recent computer for.

With prices so low now a days, I don't see a point in buying a used computer.

Find out the hardware requirements of the software you want and then try somewhere like ebay.

Another alternative for cheap computers is Dell.com. More expensive than a second-hand computer, but at least you know it works and doesn't need a complete reinstall of the operating system or you find that the all-important serial port you really need is broken.

Check MicroCenter and others for reconditioned used equipment. MicroCenter was selling reconditioned XP laptops in the $350-$400 price range. They also sell desktop units.

Laptops have generally "low end" audio chips with less linearity, higher distortion and a bad noise ratio. Don't trust the manufacturer, when it is called the "ultimate multimedia solution". Pay attention for the connections, "line-in" could be just single channel (mono), mic-in is often not possible cause the mic is build-in, and with line-in the signal is often too low! When expecting good results, you should think about an external sound solution (connected via USB).

Therefore, you should check the laptop for enough USB connections. If one of these new small devices like Asus EEE Pc and others offer enough performance, I don't know.

Re: "bare bones"computer

Hey James,

I do quite a bit of audio "clean up" digitally and support for old scratchy ministry tapes and other barely audible ancient ill cared for cassette tapes recorded in third world locations.

I have some advice. First of all processor speed is significant as it will make your life easier if the software you settle on uses the CPU/FPU for its main work horse. As an example,e a 500MB file might take 15 minutes to quantify the noise and then another 15 minutes to eliminate it with a lower end setup but 2 mins on a faster set up. If you have lots of time don't sweat the processor, otherwise pay close attention to program you chose to do the work.

Second, your going to need mucho disk space to process files in general - Audio files add up quickly. I use external drives for storage but do the processing on the main drive. Time data spends coming off and going back onto your storage choice adds time to the processing

Third- Depending on your operating system of choice you will want to pay attention to system ram. In the case of most audio processing software I know more is better and better usually means faster.

My personal preference for this type of application is the Apple platform as it lends itself to the creative side of the house more readily and many Linux/MacOs freeware-shareware and really fast conversion/processing software is available. Admittedly its a personal choice.

Big Proc speed - Big Ram - Big disk space, as you compromise on these items your speed to process will vary greatly try to find a happy mid ground based on your planned throughput. Nothing stinks worse than sitting babysitting a computer as it chugs a audio file for eternity.

Now for sound output - if your going analog out and using your computer as the source I suggest a higher end audio card. If your just using your computer as a digital processing house its not that significant.

Remember, depending on your source you may need an external converter or that audio card that can accommodate analog input, consider your source. Fire Wire/USB 2/analog/disc - and build for it - if your bringing it in analog you will need to boost your audio card specs as that will affect how well the data gets put on your system - again time to process.

Otherwise stick to a mid to low audio card and go big in processor speed and memory/data storage.

Most computers can handle this task fairly easy the issue Will be process time - build to suit and budget.

Hope This helps, your mileage may vary.

Totally agree with Zap, GA vote.

I do some low-end audio processing myself, usually just making drum tracks to use as practice guides, or modifying existing audio recordings to accent the percussion parts, for my occasional student.

Where Zap covered all the hardware and the preference for MAC, I would like to add my input, incase you go other than MAC.

Discounting the current Windows Vista debacle, PC's have generally become more reliable. So, although my preference and recommendation would be a MAC, if you end up going PC with a Windows OS, I recommend XP PRO as the OS.

The reason is, just as important as the hardware is... Processor Speed, RAM, Bus Speed, L2 Cache, etc... the OS is also very critical and you want one the is stable and can be easily stripped clean to run light. And of all the non-MAC OS's out there, I found XP PRO the eaisest to configure and strip down.

There is nothing worse then being in the middle of compression or some other task and having the PC start to do something on it's own.

Prior to my switch to MAC... well, addition of a MAC since I still own a PC as well, for my audio/video editing/creating I used a P4, 2.4Mhz, 512ram, XP PRO SP2 machine with a dual-boot set-up.

When working on my audio/video files, I booted only the basic OS features needed to run the PC; nothing else was loaded, no anti-virus, no internet support: I didn't even have it hooked to the net.

It ran very clean, was fast enough, and very stable. When I wasn't working on my files, my alternate boot setup loaded the OS normally, loaded my anti-virus, etc.

I've since retired that machine to my niece, but it did serve me well.

The price point may be off but it should be noted all the new Mac's can run the latest windows op-system natively. this is due to the Intel inside. I personally enjoy my multi-platform computer which readily boot in Windows XP - Vista - Linux ( all varieties) and of course MacosX. Since it is a native run there are no longer any pesky emulation issues and the advantage is you can use your machine in the strongest software suite for your application. Its important to note this ability includes only Intel processors equipped Mac computers. Which includes all the latest models. I would only question the price point as there is a good chance they may exceed your stated budget and work intention. When you look at the total package and are able to run your favorite windows flavor native your really getting two or in my case three machines in one. So that makes it - for me - the natural choice.

Again your milage may vary.

Hello Zap,

I too do quite a bit of audio clean up and editing of ministry media. Though the products the poster intends to use do not require high performance equipment.

I was with ya right up to the comment about MAC. Many do feel the same but I use the Intel Q6600 processing equipment. Yes and I pay for stuff like Sony sound forge and Adobe audition editing products. I gotta say I tried the free stuff but I couldn't get here from there.

God Bless

I don't mind if you disagree. After I purchased my latest Mac and changed my process time from 8-7 mins per 45 mins of analog audio conditioning to two minutes start to finish in addition to giving me a ton of video capability. I'm sold. Many freeware/shareware stuff rocks and unlike the tendency of some windows setups depending on hardware/software configuration windows counterparts the mac seems tolerant enough of silly code to run some interesting things without crashing and burning - LOL.

I'm at work now so I cant remember my first line of attack software - its freeware Ill get it when I get home and share it with you. Its really a silly little app. but its noise reduction algorithms is pretty darn good for all but the really bad stuff. I have the adobe products and some bias products as well but most often time me and my freeware rock just fine. In addition the reason I mentioned the freeware option is his stated budget. Adobe thinks a lot of their systems and software.

It should also be noted my Mac shares the desk with an xps710 desktop stacked - the company insists. Its a good computer super fast ( as in about the same general speed of my new mac) but suffers from the crash syndrome and when I see them side by side I am further convinced that Microsoft needs to do more work in the OS zone as I'm sure you would agree.

Nothing like investing 1 hour into a video project only to have your windows box crash. I should state I'm not a mac evangelist. I am however a strong user and prefer a more stable OS and for now thats Linux and mac.

Your milage apparently varies-

be blessed

I build some gaming computers, and you may want to take a look at places like tigerdirect.com that offers barebones kits at a very low price, then you can purchase the audio card or whatever you need. You can then load Vista (I paid $89 for home premium)/XP, or even get Ubuntu for free. They also offer "refurbished" desktops and laptops at great prices, and they usually have your stuff at your house in 2 to 3 days.

Hello James:
you seem to have gotten some good advice, however I would just like to add stay away from laptops the performance is generally slower, with less available memory per dollar spent.

One suggestion would be to order and E. machine I know there available from Fries, and if you don't have a Fries near you they have an online store. I just purchased T3656 for $250 with an Intel Celeron 440 ,1 gig of RAM , DVD burner, and a 160 GB hard drive, complete with vista basic. A 160 GB hard drive is small by today's standards but larger than most low end laptops still, it should easily be sufficient for what you're doing. This is definitely no high-end machine however it works fine and is faster than my four-year-old custom-built high and machine that expired at an inopportune moment. (My wife gets my hand-me-downs, and I just built this new quad core she definitely wasn't going to get it yet) My wife is perfectly happy the E. machine ,I recently did some clean up on some old vinyl records I was transferring to CD. I use both my quad core Pentium and the new E. machine ,I did not find a huge difference in processing times, however I was only cleaning out clicks and pops for the most part.

Also Audacity sound processing software is available for a free download and seems to perform fairly well. Don't know of any of this will help you but you might want to try the software and see if it is sufficient for your needs before spending any money.

Hello,

You may find a laptop suitable for these needs within the $250-$300 range of refurbished equipment but do yourself a huge favor and stick to Intel products at this level of audio manipulation and your experience will be pleasant.

Seek the requirements of the software highlighted below:

Clear Voice Denoiser SDK

Automatic noise reduction and speech enhancement kit


Application:

The system is used to improve communication quality in telephone, satellite and radio channels. It can be incorporated into any PC 16/32 bit Windows 95/98/NT application which processes or uses voice or any sound signal (e.g., communication equipment, multimedia equipment, multimedia software, sound processing software, microphones, recorders, etc.)

Description:

The system is implemented as a pre-processing subroutine call, it processes sound signals in digital PCM 16 bit format and is intended to remove automatically additive noise from an input signal with minimal reduction in signal quality. Useful signal (like speech) is automatically separated from background slow varying noise. The types of cancelled noise are: slow varying in amplitude and frequency properties broadband coloured white noise in sum with narrow band harmonics varying in amplitude and frequency such as, for example, office noise, street noise, car noise, hiss and hum in communication channels, noise of home and industrial equipment, slow music, etc. The rate of noise variation in time must be less than the speed of speech (or other useful signal to be retained in processed signal). The procedure is self-adjusting but the controls of the system give to the advanced user an opportunity to fine-tune the system by choosing the best degree of noise reduction.
Important features:
  • Up to 30 dB signal-to-noise improvement
  • Single tone reduction: > 50 dB
  • White noise reduction: > 20 dB
  • Selectable frequency banwidth up to S audio sampling rate

Languages processed:

Any
Type of processing:
Continuous and adaptive removal of background noise from speech. Programmable noise reduction parameters. Hiss and rumble additional filters, frequency response forming filter.

Hardware/software requirements:

Pentium 200 or higher, Windows 95/98, RAM 16 Mb, HDD > 2 Gb, Creative Sound Blaster. The system uses only single input (e.g., hands-free car microphone or speakerphone microphone); Required memory: 8N float cells, 4N integer cells, N typically equals to 250-500.
The system is implemented in MS Visual C++ 5.0. All DLL interface functions are declared as extern "C".

Distribution:

Commercial product. May be ordered directly from
