Change logs

v2.5.8

  • Changed adjustSoC_mq for A14 and later clover not to round I/O parameters
  • Adjusted cfq I/O parameters for SDM69x devices

v2.5.7

  • Changed head ahead buffer sizes from 16960 kB to 17000 kB to reduce I/O jitter
  • Adjusted NrRequests of I/O scheduling
  • Changed dirty_ratio and dirty_background_ration to be 100 to reduce jitter
  • Adjusted re-sampling parameters for old devices

#v2.5.6

  • Added "compatible Magisk-mirroring" message for incompatible Magisk variants

#v2.5.5

  • Tuned the USB period size for SDM845 devices (2500 usec to 2250 usec)
  • Tuned the USB period size for other devices (to 2250 usec)
  • Fixed logically wrong selinux prop settings (no meaning for magisk's magic mount mechanism)
  • Added checking incompatible Magisk variants

v2.5.4

  • Tuned the USB period size for Tensor devices (2625 usec to 2250 usec)
  • Fixed for Pixel 8's

v2.5.3

  • Changed the re-sampling parameters for Galaxy S4 to the general purpose ones (optimized for 3.5mm jack; not USB DAC's)
  • Reduced I/O scheduling jitter on Tensor and SDM660 devices
  • Reduced CFQ I/O scheduling jitter on Qcomm devices

v2.5.2

  • Tuned tunables of I/O scheduler
  • Added warning messages for unneeded magisk modules

v2.5.1

  • Stopped Tensor device's AOC daemon for reducing significant jitter
  • Optimized "extras/jitter-reducer.sh" for reducing I/O scheduling jitter on Tensor devices

v2.5.0

  • Optimized for Tensor devices by tuning GPU & I/O scheduling and replacing their stock audio policy configuration
  • Hid preinstalled "Digital Wellbeing" feature for reducing significant jitter (please uninstall this manually if remaining as a usual app)

v2.4.2

  • Optimized "extras/jitter-reducer.sh" for reducing I/O scheduling jitter
  • "extras/jitter-reducer.sh" now confirms and sets the cpu scaling max freq to its available max (sometimes the scaling max freq has been lowered before by a controller on some devices)

v2.4.1

  • Added support for ColorOS (experimental)

v2.4.0

  • Fixed some SELinux related bugs for Magisk v26.0's new magic mount feature
  • Diabled pre-installed Moto Dolby features for reducing large jitter caused by them

v2.3.2

  • Added support for Tensor devices to bypass their spatial audio feature for reducing jitter distortion

v2.3.1

  • Added support for MTK A12 vendor primary audio HAL for reducing USB audio jitter
  • Fixed a bug of DRC removing on phh GSI's (umounted in the boot process of phh GSI's)

v2.3.0

  • Nullified volume listener libraries in "soundfx" folders for disabling slight compression (maybe a peak limiter only on Qcomm devices). Tuned for "mq-deadline", "kyber" and "none" I/O scheduler (latest kernel common schedulers?)
  • Added support to the Nyx kernel 4.19
  • Restructured source codes to be sharable with the jitter-reducer.sh in USB_SampleRate_Changer, audio-misc-settings and drc-remover

v2.2.1

  • Adjusted a USB transfer period of the USB HAL driver for reducing jitter

v2.2.0

  • Tuned kernel tunables by assuming an audio scheduling tunable "vendor.audio.adm.buffering.ms" to be "2"
  • Adjusted a USB period to reduce jitter

v2.1.8

  • Disabled the Android doze system itself for reducing jitter considerably even though battery optimizations of app's are effective
  • Tuned kernel tunables for SDM 8 series, MTK Dimensity's and Galaxy S4 (LineageOS 18.1)

v2.1.7

  • Changed resampling parameters for A12 or later (not having an aliasing processing bug)
  • Tuned I/O scheduler tunables

v2.1.6

  • Improved tunable values of the deadline I/O scheduler

v2.1.5

  • Fixed a bug that DRC was not detected when updating from an old module
  • Tuned parameters of the I/O scheduler

v2.1.4

  • Resampling quality changes from attenuation 140dB & length 320 to 160dB & 480

v2.1.2

  • Improved AudioFlinger's resampling quality (stopband 140dB, cutoff 91%)

v2.1.1

  • Enhanced the vm jitter reducer to handle "swap_ratio" and "swap_ratio_enable" for Snapdradons
  • Optimized tunables of the I/O jitter reducer
  • Added LICENSE
