Fixing Logitech trackball performance
I love these Logitech Marble Mouse trackballs, I have one for every computer. After a few years they slow down physically. Cleaning the dust off does not help enough, something different needed to be applied. I’ve been researching lubricants and oils, doing some tests with households; but I think I’ve found the perfect fluid. Ian Gomes of Union Sound Company made a recommendation a few years back for Penny and Giles faders. A quick amazon search lead me to Lucas Silicone Shock fluid. I must report that it is the perfect product for this application. If you need a drop, I’ll send you a q-tip of it in the mail.

On Compressing the English Language
Someone picked my brain the other day looking for a technique to compress language files.
After walking away to think about it… my method was to re-order the ASCII code to the letters by their frequency and the most common words by their frequency.
Where lowercase e is stored as an ASCII value using 1 byte
ASCII e = 0x61 = 0b1100001 = 7 bits
vs
APK e = 0x1 = 1 bit
… this method stores an E in 1 bit. This is similar to the Huffman Code with the addition of whole words being included in the code.
For example:
“because” is the 94th most used word in the english language and in this method is stored in 7 bits.
I don’t know if this has been done before… but I would imagine it could compress Language files substantially.
I have thought about a third addition of using the most used 2 or three letter combinations commonly used.

Music Note Frequency Calculator With Cent Adjustment
A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”
Sounded like the kind of math challenge I like:
The answer is 452.893Hz
To test and confirm that it’s calculating properly, this is up 100 cents making G# 440
This is down 100 cents making A# 440
Here is a link to the excel file

sound guy Xmas idea: APx515 2-Channel Audio Analyzer
This would be a dream for the test bench. Simple, robust effective analysis tools! I would be happy with an old system one… but this would be on the shelf in a heartbeat.
The APx515 is a high performance audio analyzer optimized for production test. APx515 has a typical THD+N of –106 dB, a one million point FFT with 24-bit resolution, and 192K digital I/O. It is a best-in-class instrument for its combination of speed, performance, automation, and ease-of-use.
APx515 is a significant product because it delivers the performance and reliability of Audio Precision at a production-level price.
APx is the fastest audio analyzer in the world, returning 21 audio measurements in as fast as 1.2 seconds. It is also the easiest to use, with one-click measurements, custom reporting and sophisticated automation without any programming. A full API and LabVIEW driver is also provided.
This speed and ease-of-use means test will never be a bottleneck, and production line managers can achieve reliable, consistent results compared to the current low-cost alternatives like a distortion analyzer.
For companies outsourcing their production, requiring APx515 on the production line gives tighter control over production, ensuring manufacturers are meeting their contractual requirements.
