  • Background audio playback. The application continues music playback even when the window is minimized or when the user operates other applications. Playback controls remain accessible from the system tray and through multimedia keyboard shortcuts.
  • Syllable-level lyric synchronization. FocalSonic displays song lyrics with syllable-by-syllable highlighting in real time. The feature includes multi-language support and allows simultaneous display of translations alongside the original lyrics.
  • Pitch-preserved speed control. Users can adjust playback speed from 0.5x to 2.0x without altering the original pitch of the recording. This function utilizes real-time time-stretching algorithms.
  • 10-band graphic equalizer. The tool allows frequency response modification with adjustable bands ranging from 32 Hz to 16 kHz. Users can save custom presets or select from predefined configurations for specific music genres.
  • Impulse response convolution processing. The audio engine supports convolution with impulse response files to simulate room acoustics, speaker cabinets, or microphone characteristics. Users can load custom WAV files for personalized sound shaping.
  • Parametric reverberation. The reverb module provides independent control over decay time, predelay, room size, and diffusion. Parameters are adjustable with precise numerical values for reproducible settings.
  • Discord Rich Presence integration. The application displays the currently playing song on the user's Discord profile, including artist, album, cover art, and playback time. The feature respects configured privacy settings.
  • Chromecast support. FocalSonic can stream audio directly to Chromecast devices on the local network. Streaming maintains lyric synchronization on compatible receiver devices.
  • Local cache music library. The program caches metadata and cover art from the Apple Music library to accelerate navigation. The cache updates automatically when changes are detected in the remote library.
  • Configurable keyboard shortcuts. Users can assign custom key combinations to control playback, navigation, and audio adjustments. Shortcut profiles can be exported and imported between installations.
  • Technical metadata viewer. The interface displays detailed information about the currently playing file including sample rate, bit depth, encoding format, and content type (stereo or surround audio).
  • Compact window mode. The interface can be reduced to a minimal size displaying only essential controls and the current cover art. This mode remains always visible above other applications.
  • Independent channel equalization. Users can apply separate equalization adjustments for left and right channels. This feature allows compensation for hearing perception differences between ears.
  • Manual lyric synchronization. For songs without synchronized data, users can load LRC files and manually adjust timing synchronization with millisecond precision.
  • Audio configuration export. All audio processor settings, including equalization curves and reverb parameters, can be exported to text files for backup or sharing between users.
  • Resource usage monitor. The statistics window displays real-time CPU, memory, and network bandwidth consumption by the application during playback.

FocalSonic development began in 2022 by a team of independent developers with experience in Windows multimedia applications. The application is primarily written in C++ using the Qt framework for the graphical interface. The custom audio engine was developed from scratch utilizing ASIO and WASAPI libraries for low-latency access to Windows audio hardware. Digital signal processing for effects including reverb and convolution is implemented through algorithms optimized with SIMD instructions.
