    NoiseGator (Noise Gate)

    NoiseGator (Noise Gate)

    A simple noise gate app intended for use with VOIPs like Skype.

    Ever wanted to cut out background noise when talking with others on Skype? Now it's possible! NoiseGator is a light-weight noise gate application that routes audio through an audio input to an audio output. In real-time the audio level is analysed and if the average level is higher than the threshold the audio bypasses as normal. However, if the average level goes below the threshold, the gate closes and the audio is cut. When used with a virtual audio cable it can act as a noise gate for a either a sound input(microphone) or sound output(speakers). Can also be used to gate noise from your own mic or play your microphone through your speakers. REQUIREMENTS: - Java 7 or higher for Windows. - Java 6 or higher for Mac. Java 7 recommended. - A virtual audio cable is required for use with VOIPs: For Windows users I recommend the VB-Cable driver (http://vb-audio.pagesperso-orange.fr/Cable/index.htm). Mac users can use SoundFlower.

    NetGuard

    NetGuard

    A simple way to block access to the internet per app

    NetGuard is an open-source Android firewall app that lets users control internet access on a per-app basis without requiring root access, making it a straightforward and flexible way to improve privacy and data usage management on mobile devices. By creating a local VPN service on the device, NetGuard intercepts and selectively blocks or allows network traffic for individual applications and addresses, supporting both Wi-Fi and mobile connections according to user preferences. This means you can block internet access for specific apps to save bandwidth, extend battery life, or prevent unwanted background connections while still letting other apps communicate normally. NetGuard’s interface is simple, with toggles to allow or deny access and optional settings for screen-on behavior, roaming, system apps, and notification of internet usage, giving users fine-grained control over network behavior.

    Join any Minecraft Bedrock Edition server IP on Xbox One

    On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily.

    FadCam

    FadCam

    Open-source, ad-free Android multimedia recorder with background video

    FadCam is an open-source Android multimedia recorder designed around privacy, customization, and ethical use. It started as a seamless background video recorder, but its scope now includes dashcam-style recording, screen recording, live streaming over local networks, and remote camera control. The app is ad-free and built for users who want practical recording tools without relying on commercial surveillance-style apps. It provides options for video quality, watermarks, internal storage, gallery saving, and playback inside the app. Its cloud and remote-control capabilities make it useful for legitimate workflows such as personal safety, travel recording, device monitoring with consent, and local media capture. Because the project can record in sensitive contexts, its responsible-use framing is an important part of its identity.

    Hypatia

    Hypatia

    A realtime malware scanner

    Hypatia is a free and open-source malware scanner for Android that aims to provide on-device, real-time scanning with minimal battery and resource impact using signature-based detection inspired by ClamAV style databases. Designed as an Android app, it scans user filesystems and installed applications either on demand or in real time when files are written or renamed, operating completely offline aside from occasional signature database downloads. The project is offered under an AGPL-3.0 license and is archived in its original repository, reflecting a historical effort to create a community-reviewable FOSS security tool for Android devices. Hypatia’s design targets performance and efficiency, keeping memory usage modest and enabling users to control which signature sets are active. Its real-time file observation uses multi-threaded scanning to leverage device CPU resources while striving for a negligible user experience impact.
