# Changelog ## v1.4.0 ### Break Change - Requires `ESP32-P4` chip version >= 3.0 for assembly optimization support ### Features - Added `reverb` (room reverb) effect to simulate natural sound reflections in an enclosed space - Added `delay` (echo) effect to produce delayed copies of the input signal with configurable feedback decay - Added assembly optimizations for `sonic` on `esp32s31` and `esp32p4`, improving performance by 50% - Added assembly optimizations for `rate_cvt` on `esp32s31` and `esp32p4`, improving performance by 4× - Added `esp_ae_alc_set_transit_time` API for `ALC` ## v1.3.0~1 ### Bug Fixes - Fixed link errors caused by missing `gmf_fft` linkage (undefined references to `esp_gmf_fft_init`, etc.) ## v1.3.0 ### Features - Added `howl` (howling suppression) effect to detect and suppress acoustic-feedback howling - Supported `esp-audio-effects` for `esp32s31` - Replaced server-based test data read/write with `wifi_fs` I/O to host PC folder over Wi-Fi ## v1.2.1 ### Features - Removed the range limitation of `Mixer` weight ### Bug Fixes - Fixed rate convert reset have crash when input and output samplerate is same ## v1.2.0 ### Features - Added audio effects module for `DRC`, `MBC` - Added `esp_ae_xx_reset` function for all effect modules - Added per-stream enable/disable control for `Mixer` - Added esp_audio_effects demo - Optimized effects implementation to reduce binary size - Added refine code and license for test app ### Bug Fixes - Fixed an issue where `ALC` failed to operate correctly when the input level was too low - Fixed `FADE` module reset not taking effect - Fixed a bit-depth conversion error when converting 8-bit to 24-bit ## v1.1.0 ### Features - Supported `esp-audio-effects` for `esp32-h4` - Supported mixer outbuf is one of inbuf ## v1.0.2 ### Bug Fixes - Compile libraries using the -o2 compilation option ## v1.0.1 ### Bug Fixes - Fix `test_sonic` test code error - Remove `sdkconfig.default` have some configuration strings that cannot be detected by the latest IDF ## v1.0.0 ### Features - Initial version of `esp-audio-effects` - Add audio effects module for `ALC`, `BIT_CVT`, `CH_CVT`, `RATE_CVT`, `EQ`, `FADE`, `DATA_WEAVER`, `MIXER`, `SONIC`
