* atrac3: Tonal component coding improvements:Daniil Cherednik2018-07-024-54/+99
| | | | | | | | | - Move tonal coding in to bit allocation loop. - Tonal extraction pessimization (should be rewritten with proper psy). - Some tuning. Results: - Fixed high frequency cut while tonal component encoding enabled. - Reduce spectr holes.
* atrac3denc: isnan -> std::isnan.Valtteri Vuorikoski2018-03-311-1/+1
|
* Added validation of the -e option argument and updated help strings.Valtteri Vuorikoski2018-03-311-5/+12
|
* more strict assert - check only last BFUDaniil Cherednik2017-10-291-1/+2

* workaround problem with encoding extremely loud tracksDaniil Cherednik2017-10-291-8/+8
| | | | TODO: it looks like ugly hack, check it again
* Do not apply gain control if release in current frame was detected -Daniil Cherednik2017-10-291-1/+1
| | | | right now we can't do it.

|
* kiss_fft library added, MDCT reimplemented via FFT:Daniil Cherednik2016-09-2710-40/+908
| | | | | | - we need fft for some atrac3 features - we need fft to implement better psychoacoustics analysis - use single transform library
* fix compilation errors in case of building without utDaniil Cherednik2016-09-253-0/+20
|
* Change gaincontrol default: disableDaniil Cherednik2016-09-021-5/+5
| | | | It looks like gaincontrol feature should be reimplemented. So disable it for a while.
* Dirty implementation of atrac3 encoder:Daniil Cherednik2016-09-0247-405/+3024
| | | | | | | - no JS mode - constant quantiser for tonal components - gain controll implemented but produces some artifacts with real signals. - etc...
