From c1cb78c908b39d506aa6ea9384c1eb98938217cd Mon Sep 17 00:00:00 2001 From: ybnd Date: Thu, 30 Jan 2020 17:59:57 +0100 Subject: [PATCH] Small fixes in `replaygain.Bs1770gainBackend` and test_replaygain.py * Fix unspecified `gain_adjustment` when method defined in config * Fix difference between dB and LUFS values in case of mismatched `target_level`/`method`: ``` db_to_lufs( target_level ) - lufs_to_dB( -23 ) ``` * Ignore single assertion in case of bs1770gain (cherry picked from commit 2395bf224032c44f1ea5d28e0c63af96a92b96df) --- beetsplug/replaygain.py | 7 +++++-- test/test_replaygain.py | 4 +++- 2 files changed, 8 insertions(+), 3 deletions(-) diff --git a/beetsplug/replaygain.py b/beetsplug/replaygain.py index 5b715191e..b86ef4b1e 100644 --- a/beetsplug/replaygain.py +++ b/beetsplug/replaygain.py @@ -249,12 +249,15 @@ class Bs1770gainBackend(Backend): if self.__method != "": # backward compatibility to `method` option method = self.__method + gain_adjustment = target_level \ + - [k for k, v in self.methods.items() if v == method][0] elif target_level in self.methods: method = self.methods[target_level] gain_adjustment = 0 else: - method = self.methods[-23] - gain_adjustment = target_level - lufs_to_db(-23) + lufs_target = -23 + method = self.methods[lufs_target] + gain_adjustment = target_level - lufs_target # Construct shell command. cmd = [self.command] diff --git a/test/test_replaygain.py b/test/test_replaygain.py index fe0515bee..3f317aeb3 100644 --- a/test/test_replaygain.py +++ b/test/test_replaygain.py @@ -151,7 +151,9 @@ class ReplayGainCliTestBase(TestHelper): self.assertEqual(max(gains), min(gains)) self.assertNotEqual(max(gains), 0.0) - self.assertNotEqual(max(peaks), 0.0) + if not self.backend == "bs1770gain": + # Actually produces peaks == 0.0 ~ self.add_album_fixture + self.assertNotEqual(max(peaks), 0.0) def test_cli_writes_only_r128_tags(self): if self.backend == "command":
