STEVECOX  I'm a proud owner of Wave Editor after I fell in love with Spectre (Audiofile's audio analyzer). Both of these apps are optimized for 10.4, utilizing OpenGL and Quartz. These apps are fast!

I have an early MBP because I wanted to edit 24/96k files and that was bringing my not-so-old PB using Apple's Soundtrack Pro to a screeching halt. So I thought for more horsepower I'd get a MBP. Turns out it was way too early for Apple to have a universal release of Soundtrack Pro. Then I found out that it would not be offered separately but only bundled with Final Cut Studio. I had some experience with Soundtrack Pro so I took the plunge and got the universal upgrade in early April. My biggest disappointment early on was still very slow performance. I could open files I couldn't before but it was very slow and the processor cores weren't even being utilized that much at all. It seemed I was I/O-bound. I haven't been happy at all with the universal Soundtrack Pro release. I expected much more in the way of optimization.

In comes Wave Editor... I wasn't even looking for a new waveform editor. Not because I was happy with Soundtrack Pro but because I didn't think there was anything better out there and I had already spent a wad of cash. As I was testing Spectre from Audiofile I thought I might as well download the 15 day trial of Wave Editor to see the interoperability between their own apps. I couldn't believe how fast the app launched and loaded my files. It was trivial to add an AUNetSEnd and set Spectre to receive them. I found that I was working MUCH faster and more efficient. It was no longer frustrating working with larger files. During my trial period with Wave Editor there was a useful update. I love this app!

I am extremely pleased with Audiofile and their committment to their software. I'm spending a lot more time being productive and having fun again.

STEVECOX  I have used Spectre intensively for a couple of weeks now and it has surpassed my expectations.

I wasn't sure if the software would meet my needs but there is a free 15 day download trial with full functionality so I could put it through the paces. Compared to InspectorXL I like it much better. And the last I checked there wasn't even a mention of a universal release for Inspector. That's a big deal for me and every other Mac Intel owner. From a development standpoint I like that Audiofile used Apple's builtin OpenGL and Quartz. Many developers not dedicating themselves to this platform fail to utilize the technologies that Apple has offered. The proof is surely in the efficient code because have as many as 9 analyzers running and some with multiple traces. I can still edit audio files while I'm analyzing my results.

Spectre is a fast and extremely flexible sound analysis tool. I use it primarily to view spectrograms in order to visually confirm and help identify various animal vocalizations in a particular biome. This is not specifically what the developers had in mind when they designed these tools. Nonetheless, they have been very interested in hearing about my particular needs. While most analysis tools work as plugins, this is a separate application. I wasn't sure how this would work for me at first but with Apple's AUNetSend, it's a breeze.

I wound up purchasing Spectre even before my 15 day trial has ended. I've never posted a review previously but I wanted to share my excitement with this application. I should also mention that I bought their Wave Editor app at the same time. If there is another place on MacUpdate to review that product, I will. I purchased the full Final Cut Studio just to get Soundtrack Pro's universal waveform editor. I sure wish I could get that money back now as Wave Editor is MUCH faster.
