From f068f13e4a93a960dd2ec43a601ed839253dc0b1 Mon Sep 17 00:00:00 2001 From: georgemoralis Date: Tue, 5 Nov 2024 09:16:57 +0200 Subject: [PATCH] Ajm (#1456) * ajm: Initial ajm implementation * AJM code improvements (#1453) * Fix sideband buffer order (#1454) * ajm: Attempt to add gapless support * ajm_at9: Return superframes decoded in a single job * WIP (#1460) * Fix gapless decode and combine split buffers * Fixed linux build * fix number of samples reported with gapless decoding * fixed number of remaining samples calculation should fix the small crackling sounds that play every now and again * refactor half ajm * refactored most of ajm * refactored ajm * clang-format, in-repo libatrac9, removed debug stuff --------- Co-authored-by: auser1337 Co-authored-by: Vladislav Mikhalin
