Changed:

  1. Expand the VBR Modes range from [1 – 5] to [1 - 29].
    --When --bitres-mode = 0,
    the bitrate is determined jointly by TableVbrQualFactor & BandWidthTableVBR;
    --When --bitres-mode = 1,
    the bitrate is determined by configTabVBR.

  2. --vbr-qual-factor interface to override the internal qual-value of -m,
    allowing for fine-tuning or significant adjustments to the bitrate.

  3. --hf-snr-gate interface to increase the SNR gate above 7KHz,
    reducing the amount of high-frequency noise for lower bitrate.

  4. PNS can be enabled under VBR or SBR / PS (--pns 1 to enable PNS).

  5. Ensures that the startFreq of DownsampledSBR is lower than
    sampleRate / 2 or the stopFreq.

  6. Higher-quality resampler has been implemented for Dual-Rate SBR.

  7. The PCM read accuracy has been changed to 32-bit fixed-point.

  8. bandWidthTableVBR Select the bandwidth value based on the
    SFB at the sampling rates of 32, 44, 48, 64, 88, and 96 kHz.

  9. sbrTuningTable of 32K/44K/48KHz has been optimized &
    pnsInfoTab_SBR and levelTable_SBR for PNS in SBR mode.
