Experiment with upsample frame during GHA. 2025-05-23T21:37:04Z Daniil Cherednik dan.cherednik@gmail.com 2025-05-23T21:37:04Z urn:sha1:a1911e3bd20b4b61eafedd90aade918682b2b4bb This should improve accuracy of sinusoid extraction in case when frequency in subband placed just before Nyquist frequency. Note: we still unable to handle situation with low frequency in subband which reuired much more samples for analysis.

If we want to see only result of sinusoid extraction (tonal component) we can set only GHA_WRITE_TONAL flag. If we want to see signal after extraction we need to set GHA_PASS_INPUT and GHA_WRITE_RESIUDAL. [AT3P] Adjust number of quant units during encoding. 2025-05-03T20:07:17Z Daniil Cherednik dan.cherednik@gmail.com 2025-05-03T20:07:17Z urn:sha1:98338613d8821f592682928c1096550596cb2550 Fix missed include 2025-05-01T21:02:50Z Daniil Cherednik dan.cherednik@gmail.com 2025-05-01T21:02:50Z urn:sha1:9f2dcb7808e43ff8ff06279de42ad484202c7d12 [AT3P] Add GHA processing in to the bitstream encoding. 2025-04-26T09:19:43Z Daniil Cherednik dan.cherednik@gmail.com 2025-04-21T12:43:09Z urn:sha1:4d405b21ebfdbbdd9dfc66497b8c09e680ff958d This comit bring some glue to extract residual. Also we need additional one frame delay after pqf. Temporary use ffmpeg code for gha synth. Revert "[AT3P] Delay for 1 frame during GHA. Adjust previous frame during." 2025-04-21T13:05:37Z Daniil Cherednik dan.cherednik@gmail.com 2025-04-21T13:05:37Z urn:sha1:e240216e7616485f23f18b52573fa01be45cc6c0 This reverts commit 0265177f2d64503df609c63238d983d984938fab. It looks like previous statement about adjusting delayed frame was wrong. Commit 0265177f2d64503df609c63238d983d984938fab causes some phantom generation.
