ShizuCallRecorder

ShizuCallRecorder is a free, open-source Android application that records phone calls without requiring root access. It uses Shizuku and ADB privileges to capture audio through Android's internal interfaces. The application records both incoming and outgoing calls, separating uplink and downlink audio into stereo channels. It primarily supports cellular and VoLTE calls, with experimental compatibility for Wi-Fi calling and VoIP. Users can enable automatic recording and exclude anonymous callers or selected contacts. Supported audio codecs include Opus, AAC, and HE-AAC. Security controls help manage Shizuku activation and reduce unnecessary privileged access. The application runs only when phone events change, avoiding persistent background processes.
