    应用描述

    This app measures the RPM of an engine by analyzing the sound it makes. It uses advanced signal processing algorithms to measure the pitch of the sound and display and log the calculated RPM.

    This app will not work if the engine sounds are muffled or unstable or combined with too much other noise. The engine sound must be clear and stable and sound like a single tone. Other sounds can also prevent the engine sound from being analyzed.

    The software is configurable for 2-cycle and 4-cycle engines and includes a generic configuration for unusual cases, such as a reduction gear. The normal RPM range is 400 to 90,000 RPM, although much lower RPMs can be measured using the manual RPM matching option.

    A detailed manual is available from our support webpage.

    * Improved signal analysis calculations, making envelope detection unnecessary.
    * Use of speaker in "Match RPM sound" mode is louder.
    * Revised time-stamp in logging to reflect time of day.
    * Configurable logging interval.
    * Improved help files.

    更新日志

    Spectrum analysis has been improved to better identify the harmonics of the engine sound.

    A new Tracking mode has been added to track changing RPM over the entire 500-90,000 RPM range.

    The range of harmonics used in analysis is now selectable, using harmonics 1-16.

    The 4-cycle, 1-cylinder engine has been added to the list of stock engine configurations.

    Detection of a missing microphone for the iPod Touch has been added.
