Audio library syncing and conversion utility

Easy Audio Sync is an audio library syncing and conversion utility. The intended use is syncing an audio library with many lossless files to a mobile device with limited storage.

The program’s design is inspired by the rsync utility. It supports folder-based source to destination syncing, with added audio transcoding capability, and is GUI-based instead of CLI-based.

Features:

  • Custom FFmpeg-based audio transcoding engine
    • Multithreaded operation for fast conversions
    • 4 lossy output codecs supported: MP3, AAC, Ogg Vorbis, and Opus
  • Robust metadata parser ensures tags and cover art are correctly transferred when converting between different formats
  • ReplayGain volume adjustments
  • Destination folder cleaning (deleting files that no longer exist in the source)
  • Cross-platform Windows/macOS/Linux

HydrogenAudio presents the definitive resource for testing sample rate conversion applications. Each Sample Rate Converter (SRC) is examined against multiple revealing tests, generating an overall quality ranking. A quality ranking needs careful consideration, these tests are formulated to test modern SRC routines, as such they are very sensitive way in excess of the 24 bit (-144dB) audible range. A SRC scoring 60% could very well have inaudible defects if converted to 24 bit, so why the need for high precision testing? An example might be in the studio, audio is processed in many ways, having a clean SRC converter allows further processing steps, including amplification, without fear of audible distortion. The best SRC have distortion down below -300 dBFS, giving plenty of head room for future processing and mixing of different sources.

Here located unofficial builds of the SoX (Sound eXchange) audio tool with DSD support and other patches (including both DSF & DFF I/O and SDM sox “effect” to convert from PCM to DSD) for OS Windows only. Provided two Windows executable files for 32 & 64 bit systems. Binaries were cross-compiled on Linux using MinGW/gcc on fully static way.

  •  DSF I/O
  •  DFF I/O
  •  SDM effect to convert from PCM to DSD

MusicSync is a cross-platform tool that synchronizes your music library between devices and drives with advanced settings.

You can use it through CLI, that makes easy to sync you library with only a click using a script, or through GUI, that is more user-friendly. Here there are two examples:

python musicsync D:/Music sdcard/Music --adb --min-rating 4.5 --output-format opus --output-bitrate 128k
python musicsync D:/Music sdcard/Music --adb --min-rating 3 --min-year 2020 --output-format opus --output-bitrate
