KATSURA  for electric guitars, you need to connect it to your Mac via the audio input port on Mac, or use a guitar amp and the internal microphone on Mac.

it is not practical to try to tune an electric guitar with the internal microphone as an electric guitar does not generate loud enough sound that Mac can actually hear.

KATSURA  please use it with caution. RealZoom is not a viewer and it currently does not have a preview feature to view a small portion of the original image. it's a tool to generate a zoomed image. if you load a large image to generate an even larger zoomed image, Mac OS itself (not the app) could choke.

NOTE: RealZoom generates a very large image when the magnification is high (e.g. 6x, 9x, 12x, etc.), and the system may not be able to handle a very large image properly. Please make sure to select a portion of (or scale down) your large image and save a smaller image with your image editing application such as Photoshop, then load the small image with RealZoom.

Piano Tuner is $99 because it has the features for professional musicians and/or musical instrument technicians.

KATSURA  thanks. now i know what you mean. Universal Access is a "regular" zoom. RealZoom is a "real" zoom or whatever you want to call it. please visit my web site and take a look at the sample images.

KATSURA  having duplicate color pickers in ~/Library/ColorPickers and /System/Library/ColorPickers causes a crash. please remove one.  
(Version 1.0)

KATSURA  i'm not sure if you are talking about my Chromatic Tuner.

if anything crashes, please send the crash log to the author so that it can be analyzed and fixed.

fyi, it works just fine on my machine.  
(Version 0.6)

KATSURA  Thanks for your feedback. I'll try to make it more responsive in the next release. The pitch detection algorithm Chromatic Tuner uses is very light weight (not processor intensive) and has certain characteristics. If it doesn't detect the pitch accurately, please try to play the sound closer to the microphone and/or adjust the input volume in order to reduce the ambient noise.  
(Version 0.2)

KATSURA  Perfect Pitch looks and works great, and it has advanced features. But it consumes a lot of CPU time. Run Activity Monitor on 10.3 or Process Viewer on 10.2 to see the difference.

Chromatic Tuner is free to try, too. It's $5 to register while Perfect Pitch suggests $15 donation.

KATSURA  Here are some technical details. It's a pink/brown noise generator with a "wave-like" random amplitude moduration. Unlike the recorded real sound of ocean waves on CD's, the simulated sound of ocean waves from Ocean Waves does NOT repeat for hours. Some people may be annoyed by any noticeable repeated sound, at least I do. So I'm trying to make non-repeating simulated sound using a pseudo random function. It would be really nice if it sounds much much more realistic, like Pixer does with their animations, and Ocean Waves is probably around (or not even) "wire-frame" level so far. I'll study the sound more and try to make it better in the future. Thanks. -author
