Open Source Swift Sound/Audio Software

EeveeSpotifyReborn is an unofficial modification for the Spotify mobile application that alters client-side behavior to unlock premium-like features without requiring a paid subscription. It operates by injecting changes into the Spotify app, making it interpret the user account as having premium access and enabling functionalities that are normally restricted. The project was developed through reverse engineering techniques, including analyzing application behavior and intercepting requests to replicate premium functionality within the client environment. It also extends the base experience by adding features such as alternative lyric providers, enabling more flexible and enhanced lyric display compared to the default implementation. The tool requires users to build or sideload a modified application package, as distribution of prebuilt binaries is restricted due to legal concerns.

System audio equalizer for macOS. Professional grade Parametric EQ & volume mixer. If you feel like your audio device (Headphones or Speaker) does not have enough Bass (low frequency) punch, or vice versa, you can adjust that using eqMac. macOS does not have a direct way to access the System Audio stream, so we use the eqMac Audio driver to divert the system audio to the driver's input stream. Then eqMac captures that Input audio stream processes it, and sends it directly to the output device. Expert EQ, unlimited bands, fully customizable (Filter Type, Frequency, Gain, Bandwidth). Volume mixer, apply different volume levels per each application. Fully customize the look and feel of eqMac by changing the User Interface Colors, Feature visibility, and arrangement. Control all aspects of eqMac through a WebSocket API. Works with any programming language that supports WebSockets.

Lossless Extract for macOS and Windows is a tool for purists who demand perfect audio preservation. Designed for precision and simplicity, it effortlessly extracts high-resolution audio from Blu-ray, SACD, MKV or DVD=Audio sources. It handles Dolby TrueHD (with Atmos) and DTS-HD Master Audio preserving atmos object based meta data. Many tools decode immersive audio into PCM, which permanently destroys spatial metadata. Lossless Extract preserves the original audio stream so the immersive mix plays correctly on compatible AVRs and streaming devices. Accepts MKV, BLU-Ray BDMV, and DVD-AUDIO ISO, AUDIO_TS folders, and SACD.isos as input files. Choose your preferred output format—FLAC , MKA, M4A, DSF, DFF, or Direct stream copy and Lossless Extract will deliver pristine, bit-for-bit copies of your original audio streams. Whether you’re archiving your home theater collection or preparing high-end audio projects, Lossless Extract ensures every detail is preserved, every time. S

AudioKit is an entire audio development ecosystem of code repositories, packages, libraries, algorithms, applications, playgorunds, tests, and scripts, built and used by a community of audio programmers, app developers, engineers, researchers, scientists, musicians, gamers, and people new to programming. An important goal for AudioKit is to allow it to grow and be maintainable by a handful of volunteers. For this reason we have extensive tests that are run whenever changes are made to any AudioKit code repository. We accept and encourage Github sponsorship of the people who spend a lot of time supporting AudioKit. We want to inspire the next generation of audio app developers and we do that by highlighting AudioKit-powered apps and by creating our own apps under the "AudioKit Pro" brand including the world's most downloaded synth "AudioKit Synth One" and a host of other AudioKit Pro apps.

StageMaster places script and presentation content for a variety of programs and performances on a timeline. It can play the required video and audio, launch a DAW automatically, and send web pages, still images, and other content to an HDMI output. It can be used for single-operator control of radio broadcasts and events, as well as for automated, program-driven or slave operation in a hall. On stage, it can send a main output alongside performer-specific channels. Note that an audio interface is required to send audio from a Mac or PC to a sound system. There are many audio interface models available worldwide, and not all of them have been verified to work.

Quill is a minimalist macOS meeting recorder and transcription utility that runs from the menu bar. It captures microphone input and system audio as separate tracks, which naturally distinguishes the user from other speakers. When recording stops, both tracks are transcribed locally and merged into a timestamped, speaker-labeled transcript. The app uses an on-device Parakeet model, so recordings and text never need to leave the Mac. Sessions are stored as audio, metadata, transcript, and log files in organized folders. Its filesystem-based queue can resume unfinished jobs after relaunch and continue processing while a new meeting is recorded. Quill is distributed as a single Swift executable and supports launch-at-login installation, diagnostics, configurable output folders, and post-processing hooks.
