  • Changed dirty_ratio and dirty_background_ration to be 100 to reduce jitter
  • Changed adjustSoC_mq for A14 and later clover not to round I/O parameters
  • Adjusted cfq I/O parameters for SDM69x devices
  • Added a new re-sampler script specially tuned for DAC's under $30 and LDAC BT devices both having large non-linear amp. distortion in "Usage Samples/Resampling"

New cheapies re-sampler script could improve audio quality significantly for both DAC's under $30 and LDAC BT devices, especially when replaying 44.1kHz tracks up-sampled over 96kHz & 24bits by AudioFlinger (the system-wide mixer), but also for internal speakers receiving 48kHz & 24bits audio data (except 48kHz & 16bits).

Because its re-sampling near ideally cuts a freq. zone just above 20kHz (ultrasonic noise) made by high freq. dithering and deteriorating audible sound by intermodulation amplified by large amp. non-linearity of cheap DAC's and BT devices.

Edit: Added cheapies-hires re-sampler script for Hires. tracks through LDAC bluetooth earphones without ultrasonic noise to improve audio quality.

Edit2: Adjusted I/O scheduler parameters of Clover (A14)
