Hifi-Apps Speaker Setup 2 1.63

The Hifi-Apps application is designed to help users maximize the capabilities of their sound systems, offering a comprehensive listening experience that is easy to navigate, even for those without prior technical knowledge. Utilizing established measurement techniques, the app generates user-friendly improvement suggestions clarified by listening tests, making it accessible to a wide audience. Notably, even the built-in microphone of an Android device can yield valuable insights into sound quality. For those seeking a more refined analysis, the integration of an external measurement microphone is recommended.

This application serves as a precise tool for optimizing speaker setup. Users can connect their Android device to their sound system and initiate measurements by following guided instructions at designated listening locations while playing test signals. The app not only provides technical data but also offers automatic interpretations of results along with actionable recommendations for enhancements. Users can directly compare various configurations of speakers, listening positions, and damping materials.

Features

• Simultaneous measurement of two channels (e.g., right/left in stereo).
• Automatic interpretation of results, making them accessible without prior expertise.
• Raw data display for frequency response with adjustable smoothing levels.
• Impulse response data available (linear and logarithmic) on request.
• Difference measurements enable meaningful comparisons using an uncalibrated built-in microphone.
• Calibration capabilities for the built-in microphone through comparison measurements, provided a measurement microphone is available.
• Support for measuring microphones with calibration curve imports.
• Assessment of bass quality based on identified room modes and reflections.
• Recommendations for improving the bass range through speaker and listener positioning as well as absorbers.
• Evaluation of replay precision based on both impulse response and frequency response.
• Geometric calculation of floor reflections contrasted with measured values.
• Early reflection evaluation based on uniform impulse response.
• Rating for channel equality.
• References to the listening environment using reverberation time metrics.
• Suggestions for suitable absorbers.
• Guidance on equalizer settings and discussions on their effective use.
• Customizable thresholds and parameters for assessments and recommendations.
• The ability to export results in HTML format and access measured values in CSV format when using external memory (e.g., SD card).
