* | Improving rate control for low bitrate | Jean-Marc Valin | 2018-05-17 | 1 | -6/+0 |
| | | | | | | Using a finer table for the rate to SNR curves in silk_control_SNR(). It's now possible to have an SNR that reaches 0, so we can lower bitrate down to ~5 kbps for narrowband and 5.5 kbps for wideband. | ||||

* | Convert quotes in license headers to ASCII. | Timothy B. Terriberry | 2013-05-19 | 1 | -1/+1 |
| | | | | | | Since the last patch originally had them mangled (presumably by mailer, http server, or something else), let's just get rid of them. | ||||

* | Add support for coding signs with 0 pulses. | Timothy B. Terriberry | 2011-09-27 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | The SILK bitstream allowed coding 0 pulses in a shell block, but a non-zero number of LSb's, meaning some excitation coefficients could be non-zero, but would not have a corresponding sign. To fix this without breaking already-encoded bitstreams, this patch adds a set of sign PDFs for the 0 pulses case. This is occasionally more efficient than the normal encoding if there are a large number of coefficients with positive signs, since these cost more than 1 bit when using the > 0 pulse PDFs. It only saves 0.33 bits per second (on average: it does better at high rates), but that's probably enough to justify the two redundant ways of coding things (and it's too late now to remove the second one entirely, anyway). This patch does not include the encoder modifications required to check if this coding method is more efficient and switch to it. | ||||

* | Support for glitchles mode switching | Jean-Marc Valin | 2011-03-07 | 1 | -5/+5 |
| | | | | | | Uses a 5ms redundant CELT frame embedded into the SILK or hybrid packet to handle the switching. It's still possible to use the PLC-based method when no redundant packet is included. | ||||
