Technotes & Appnotes
Technotes and Appnotes look at various topics in audio test and measurement—sometimes a particular solution, perhaps a time-saving tip or an in-depth exploration of a difficult concept. Technotes are shorter documents that tend to look at a particular issue or problem, while Appnotes tend to examine larger sets of audio test issues, for example, all the aspects of measuring a CD player performance.
Many of the notes are specific to Audio Precision analyzers, and some to a particular instrument. However, the approaches and strategies taken in a certain testing environment are often transferable to another situation, and our customers find value even with the older notes written for legacy instruments.
