FLAC tiedostojen volumin, eli äänenvoimakkuuden muokkaus

Lontooksi asiasta on todettu seuraavaa:

To adjust the loudness of FLAC files, you can use audio editing software like Audacity, which supports FLAC and allows for volume adjustments and normalization. Alternatively, command-line tools like FFmpeg can be used for batch processing with specific volume adjustments. ReplayGain tags can also be used to adjust loudness during playback, which doesn't involve altering the audio data itself. The player needs to support ReplayGain for it to work because this is just for playback.

Using Audacity:
1. Import FLAC files:
Open Audacity and import your FLAC files.
2. Adjust volume:
Select the audio you want to adjust and use the "Effect > Amplify" or "Effect > Gain" tools to change the loudness.
3. Normalize loudness:
For consistent loudness across multiple files, you can use the "Effect > Normalize" feature in Audacity.
4. Export:
Export the modified files, ensuring the FLAC format is selected for lossless preservation.

Using ReplayGain tags:
1. Install a tool to add tags:
Use a tool like MetaFLAC or software like Foobar2000 (on Windows) to add ReplayGain tags to your FLAC files.
2. Enable ReplayGain in your player:
Ensure your audio player (many support it, including VLC Media Player) is configured to use ReplayGain tags for playback volume adjustment.
