About this app

The music player was developed with a single goal in mind: The highest possible playback quality via loudspeakers. To achieve this, two components from the high-end sector are used: a measurement program that measures the characteristics of the speakers in interaction with the listening room and a correction program that uses the results.
It plays mp3, flac... sound files from your local store (no streaming services) with digital room correction, the next evolutionary step after the equalizer.
Until now, this was only possible in the high-end range. Meanwhile, Android devices are powerful enough to measure the characteristics of the listening room and calculate appropriate corrections for music playback.

Features
- Guided measurement of the speaker and room properties
- Automatic calculation and use of digital room correction during music playback
- Simple and functional player

Options for experienced users
- Serial function for fast measurement at many microphone positions
- Fade-in of calculated reflections (comb filter) for comparison with the measurement data
- Phase: raw data, rolled up and group delay.
- Display of correction curve and predicted result
- Adjustable limitation of correction strength
- Editable target curve
- Optional partial adjustment of the correction to the smoothed frequency response of the speakers to maintain the sound characteristics
- Options for using the Excess Phase
- Frequency-dependent windowing
- Use of measurement microphones (import of calibration curve).
- Import and export of DRC files
- Export of corrected music files, e.g. for playback on high-end systems
- English and German

Pro Features
- No advertising
- Comparison of burst response, impulse response and frequency response with and without DRC
- Listening tests for burst response, adjustment of dealy between right and left channel
