DSP-Quattro Testimonials.

What press say:

DSP-Quattro reaches beyond the boundaries of traditional audio-editing software. In addition to the typical sample-editing tools, it features multitrack recording, simultaneous playback of multiple audio files, real-time hosting of virtual instruments, and real-time effects processing of audio input. ... DSP-Quattro is an absolutely outstanding piece of software and an incredible value. It offers features and performances on par with or exceeding sample-editing software costing four or five times as much. The documentation is complete and accurate. The user interface is well thought out, and key commands are provided for most often used operations. Any one of its five basic function - sample editor, soft-synth rack, real-time effects box, mastring tool or audio-CD burner - is easily worth the price tag.

This 'modular' digital audio editor delivers outrageous value and innovative design... DSPQ does all expected editing/mastering functions ... but if (for example) you are a sample developer, this program is aces. ... For years, Windows users have enjoined a wonderful set of editing programs, while on the Mac... But DSP-Quattro has some features that aren't available on any the Windows editors, while setting the bar higher for what can expect from this type of program. At this price, the cost effectiveness is unbelievable - but download the demo and you will believe. This is an exceptional piece of software.

Electronic Musician 2005 Editor Choice - Audio Editing Software (2-Tracks). True bargains are a rarity in professional-grade music software. When one does come along, it is a compelling candidate for an award. Based on features and price, DSP-Quattro would appear to be a good deal, but it wouldn't be an award winner if its performance were unimpressive. Fortunately, the program delivers outstanding quality as well. In our estimation, that makes it a true bargain - and an EM Editors' Choice award winner ... In short, this little monster is one of the best deal of the year.

FOR: + Excellent sample rate conversion + UI much more responsive + Good value + OS9 and OSX compatible - Sample rate conversions are notoriously difficult to carry out accurately. As a result, algorithms vary quite bit in terms of speed of execution and audio quality. generally speaking, higher quality conversions take longer to carry out, but sonehow the guys at i3 have come up with a sample rate conversion technique - based on a linear phase technology - that can be executed quickly yet still produces excellent audio results. We tried it out on a couple of high resolution clips and we very much liked what we heard ... it will almost definitely satiate the audio editing appetite of all but the most power-hungry Mac User

Stereo Editing for the Mac, with class. The signal routing capabilities of this program are second to none. ... There aren't any other programs that give you the number of options for routing and processing audio that this one does, at any step of the way through the program. DSP-Quattro deserves your serious consideration when you're looking for a dedicated editing and CD burning application. You'll get a virtual processing and virtual instrument application into the bargaing. To top it all off, DSP-Quattro is extremely reasonably priced. It's tough to beat.

... To my mind, this is an absolutely unmissable bargain and perhaps a real cause for concern among i3's competitors. DSP Quattro is already an impressive and powerful application, which could develop into a real giant-killer. If you're in the market for a Mac audio editor, you owe it to yourself to try it.

I can honestly say that Quattro goes from strength to strength. It really is the most amazing program and I am never at my workstation without it open for one job or another. Why every professional producer in dance music doesn't use it, I don't know - maybe one day they all will. Without Quattro, I doubt if I could make records any more ! ;-) Keep the good work up.

Elainie Lillios

Thanks SO much. I really love DSPQuattro!

I am a proud owner and user of DSP-Quattro. I'm a live sound engineer and I use it to record shows and then prepare and burn them to CD for the band. Out of all the 2-track editing software out there I find yours the easiest to use and much more in my price range.

Hi! Enjoying your excellent program!

Steve Schiller

I love the program -- very intuitive, very smooth, very pleasing GUI.

Ron Curcio

track files into shape, DSP-Quattro rules all, and it's relatively inexpensive. Best of all, it's resampling function sounds wonderful (when set on Excellent), and it's fastfastfast. It's got a great batch processor, and it's cheap, too. I just finished making up a complex custom soundfont for a DS game, it batch-processed more then 300 tiny little 24/44 files down to 16/22 in no time, and kept the loop points intact (!!!)

Duncan Watt

I'm against a scary deadline (I'm a game composer), making a custom soundbank for a DS game... Your loop x-fade window is amazingly simple and effective - I wish I had this two years ago.

Robin Proper-Sheppard

thanks for the great editor!

Roy Cherryhomes

Texas, USA

Greetings from Dallas Texas. I really love the upgrades to 2.0 which you posted in December!

Ricardo Godoy

Everything went perfect with no problems wow I love this program so much ... My PC friend was very pleased with the stability of DSP Quattro ! And also was very jealous that there isn't a PC version. Anyways Thank you so very much for your great e-mails!

George Foster

I believe your program is the best value in recording software.

Manuel Rettinger

UBIK Sound

I can't express how much I admire this software. Thank you for your hard work.

So, the conclusion is: Congratulations! DSP-Quattro is clearly the current winner in my resampling tests and is what I will use from now on for any resampling.

I've just got back from the Madonna tour and got my G5 up and running... Thank you for all your help and brilliant software!!!

Steve Sidelnyk

Madonna, Seal


Some time ago I became a user of DSP-Quattro... I had some problems early on that you helped in rectifying for which I never thanked you... I just wanted to take the time to say thanks for helping me in such a timely fashion and to congratulate and compliment you on a truly outstanding audio application; I don't know how you got this to be both realtime and stable-WOW. I also think that the ability to process audio while playing a vsti via midi and record the resulting work is outrageous... A wonderful, powerful program that's simple to use doesn't come along often enough!!!!

DSP-Quattro made it possible for me to create my CD: Modal Soul: Keyboard Jazz & Contemporary Piano for Contemplation and Delight. Modal Soul was recorded, edited, mixed and mastered entirely on DSP-Quattro. Not only is this software excellent, it is also readily learnable by anyone (such as myself) who has had no prior experience in digital recording. Additionally, customer support is exceptional! The few questions I had about using DSP-Quattro were quickly, and always correctly, answered. I cant say enough good things about DSP-Quattro. Suffice it to say that I am very grateful for the obvious thought and care that have gone into making DSP-Quattro so useful and excellent. It is truly superb!
