DescriptionB2B Rocket's SDR AI Agent is a powerful AI-driven tool designed to revolutionize B2B cold email marketing. It automates lead generation, email validation, and customer engagement to dramatically enhance your marketing efficiency. With features like data cleanup, intent data, email warm-up, and an AI auto-reply system, this tool simplifies and scales your outreach efforts. In addition to the SDR AI Agent, B2B Rocket offers free tools like a Spam Detector, Meeting Scheduler, and Unified Calendar to help you manage your communications and schedules effectively.Clownfish Voice Changer is a free Windows voice-effects application from developer Bogdan Sharkov, whose official site identifies Shark Labs, Sofia. It changes audio at the microphone capture-device level, so applications using that configured input can receive the effect. Current main download packages target Windows 10 and 11. The main app includes pitch and character effects, a sound player, a music player, keyboard controls and VST plugin support. The base effect list should not be confused with a library of AI-generated voices. Its documented VC Client connection uses a separate external voice-conversion tool; the external software, model setup and permissions are additional considerations. Installation requires administrator rights and choosing the capture device to modify. The official instructions say the default capture device is selected initially, with other devices available through Setup. Choose the installer matching the operating system and the VST variant you need. Enable a voice effect, use Hear microphone to preview it, and test the actual microphone in your call or game before relying on the result. Clownfish's separate Terminal Edition routes an audio input to a chosen output and lists Windows, macOS and Linux downloads. It requires additional software to create a virtual audio device. Those downloads do not mean that the main Windows graphical app has the same interface and setup on Mac or Linux. The official site includes a free software license notice permitting use and redistribution subject to its conditions. That software permission does not automatically license outside plugins, voice models, music or sounds. Use the official download page for the current edition and setup notes. Compare Voicemod for a desktop voice catalog and soundboards with Free and PRO access; Clownfish is an alternative when a Windows device-level effects workflow fits your needs.
