Librempeg ~ Multimedia Libraries & Toolsets

Posted by tom2tec on

Librempeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries:

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools:

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

CamillaDSP ~ IIR & FIR Engine For Crossovers & Room Correction

Posted by tom2tec on

A tool to create audio processing pipelines for applications such as active crossovers or room correction. It is written in Rust to benefit from the safety and elegant handling of threading that this language provides. Supported platforms: Linux, macOS, Windows.

Audio data is captured from a capture device and sent to a playback device. Alsa, PulseAudio, Jack, Wasapi and CoreAudio are currently supported for both capture and playback.

The processing pipeline consists of any number of filters and mixers. Mixers are used to route audio between channels and to change the number of channels in the stream. Filters can be both IIR and FIR. IIR filters are implemented as biquads, while FIR use convolution via FFT/IFFT. A filter can be applied to any number of channels. All processing is done in chunks of a fixed number of samples. A small number of samples gives a small in-out latency while a larger number is required for long FIR filters. The full configuration is given in a YAML file.

SOX-DSD ~ SoX With DSD For Windows.

Posted by tom2tec on

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

NSMusicS ~ Modular Multiplatform Player

Posted by tom2tec on

The NSMusicS plan is a multi-modal smart music software based on Electron and WPF, supporting multiple platforms.

  • Windows Professional MusicPlayer++
  • Tens of millions – song level of Music Library Management on NAS
  • Music and Entertainment Scenes (Recording karaoke and scoring…)
  • Windows Music IDE, similar to Adobe Audition:
    1. Identify songs module based on sound fingerprint technology (also open sourced as a separate project model)
    2. Guessing Your Favorite Module Based on Big Data User Behavior Analysis
    3. AI singing module based on NLP, replacing the sound of the song with your own (also open sourced as a separate project model)
    4. AI music notation module based on NLP (also open sourced as a separate project model)
    5. AI extraction of audio lyrics synchronization information based on nlp (breaking copyright barriers such as Krc and Qrc)
    6. Implement functions such as NSMusicS singing bar scoring and evaluation

FlexASIO ~ Flexible Universal ASIO Driver

Posted by tom2tec on

FlexASIO is a universal ASIO driver, meaning that it is not tied to specific audio hardware. Other examples of universal ASIO drivers include ASIO4ALL, ASIO2KS, ASIO2WASAPI.

Universal ASIO drivers use hardware-agnostic audio interfaces provided by the operating system to produce and consume sound. The typical use case for such a driver is to make ASIO usable with audio hardware that doesn’t come with its own ASIO drivers, or where the bundled ASIO drivers don’t provide the desired functionality.

While ASIO4ALL and ASIO2KS use a low-level Windows audio API known as Kernel Streaming (also called “DirectKS”, “WDM-KS”) to operate, and ASIO2WASAPI uses WASAPI (in exclusive mode only), FlexASIO differentiates itself by using an intermediate library called PortAudio that itself supports a large number of operating system sound APIs, which includes Kernel Streaming and WASAPI (in shared and exclusive mode), but also the more mundane APIs MME and DirectSound. Thus FlexASIO can be used to interface with any sound API available on a Windows system. For more information, see the backends documentation.

Among other things, this makes it possible to emulate a typical Windows application that opens an audio device in shared mode. This means other applications can use the same audio devices at the same time, with the Windows audio engine mixing the various audio streams. Other universal ASIO drivers do not offer this functionality as they always open audio devices in exclusive mode.

MusicSync ~ Synchronize Music Libraries

Posted by tom2tec on

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
