3D "enhancement" is available on all imx233 platform, and also on platforms with the WM8978 codec (gigabeats) and WM8750 codec (MPIO HD 200/300). I used different texts for different codecs because (in theory) they do different "things". Change-Id: I62ecb075f7594427491b6be83cfa80f763566aba
2015-11-15YH8xx,YH9xx: Keymap improvementSebastian Leonhardt1-1/+1
The main "innovation" in this patch are two "virtual buttons" for the record switch on YH92x targets. When the switch state changes, a single BUTTON_REC_SW_ON or .._OFF button event will be generated. Thus keymap code can react on switching, but not on the actual state of the switch. Wherever sensible, the following user scheme is applied: - use PLAY as confirm button - use REW button or Long REW to exit - use REC (YH820) or FFWD (YH92X) as modifier key for button combos Change-Id: Ic8d1db9cc6869daed8dda98990dfdf7f6fd5d5a1

2014-01-13Implement volume limiter featurePurlingNayuki1-0/+6
Add a "volume limit" parameter to the configuration file. The maximum value of volume setting in sound menu will be limited to the same as volume limit. Also each time when setvol() is excuted, Rockbox will check if the global_settings.volume value larger than global_settings.volume_limit. If larger, take the value of volume_limit instead. The volume_limit argument shares the same maximum and minimum values with volume argument, while taking the maximum volume as its default value.

2013-12-15DSP Compressor: Sidechain, Exponential Atk/RlsRyan Billing1-0/+3
This is an improvement to the current compressor which I have added to my own Sansa Fuze V2 build. I am submitting here in case others find it interesting. Features added to the existing compressor: Attack, Look-ahead, Sidechain Filtering. Exponential attack and release characteristic response. Benefits from adding missing features: Attack: Preserve perceived "brightness" of tone by letting onset transients come through at a higher level than the rest of the compressed program material. Look-ahead: With Attack comes clipping on the leading several cycles of a transient onset. With look-ahead function, this can be pre-emptively mitigated with a slower gain change (less distortion). Look-ahead limiting is implemented to prevent clipping while keeping gain change ramp to an interval near 3ms instead of instant attack. The existing compressor implementation distorts the leading edge of a transient by causing instant gain change, resulting in log() distortion. This sounds "woofy" to me. Exponential Attack/Release: eMore natural sounding. On attack, this is a true straight line of 10dB per attack interval. Release is a little different, however, sounds natural as an analog compressor. Sidechain Filtering: Mild high-pass filter reduces response to low frequency onsets. For example, a hard kick drum is less likely to make the whole of the program material appear to fade in and out. Combined with a moderate attack time, such a transient will ride through with minimal audible artifact. Overall these changes make dynamic music sound more "open", more natural. The goal of a compressor is to make dyanamic music sound louder without necessarily sounding as though it has been compressed. I believe these changes come closer to this goal. Enjoy. If not, I am enjoying it Change-Id: I664eace546c364b815b4dc9ed4a72849231a0eb2 Reviewed-on: Tested: Purling Nayuki <> Reviewed-by: Michael Giacomelli <>
