Thafknar is an audio recorder and player and a tool for adding reverb to files and to audio streams (Audiobus, IAA, AUv3; the latter being an in-app purchase). Upload audio files by iTunes File Sharing or by Document Interaction, or create recordings with the app's built-in audio recorder. Play or save the files with added reverb. Use play through mode for realtime reverberation. The reverb can be created by an iOS Audio Unit or by the app's convolution reverb engine (iPad 4 or better is recommended for realtime usage).
