RE-1 - Tape Echo RE-1 is a full featured virtual Tape Machine capable of delivering authentic tape based echo and chorus effects but it doesn't stop there. With it's interactive tape player, sample, loop and overdub features it's possible to use it like a virtual tape recorder, sample player, looper or simply as a master effect. Overview: - Virtual Tape deck including 3 individually controllable read heads, variable delay time and feedback - Interactive user interface and realtime visualisation of various parameters related to the tape simulation - Dedicated controls for Wow, Flutter, Color, Tape Hiss & saturation amount - Tape Loop mode with overdub, tape reverse and time-stretching - Sample/Loop library loads wave files onto the virtual tape loop - Transport and Tempo Sync - Stereo Spread & Stereo Panner - Input processing: Highpass filter - Output processing: 2 band eq Tape Echo: - Authentic tape echo emulation - Multi-tap delay with 3 individually controllable read heads - Color Control adjusts the echo's tone from dark to bright - Delay Time: 5ms - 1000ms (or 1/32th to 1/1) - Wow & Flutter - Tape Hiss and Saturation - Stereo spread - Stereo panner Looper / Sample Player: - Uses the tape like a traditional looper with unlimited overdubs - Configurable Loop length with 1 - 8 bars and tempo sync and tape reverse - Tape transport can be linked to the host's transport controls - Time stretching keeps loops in sync - Samples/loops can be loaded onto the tape directly - Samples can be created from the tape loop and stored in the sample library at any time - Factory content includes a variety of loops grouped by style - Samples/loops can be imported from and exported to other apps Connectivity: - Standalone - AUv3 - InterApp-Audio - Audiobus - Ableton Link - MIDI (Tempo, CC, Program Change) - Requirements: - iOS 11+
Speaker Positioning
Read full descriptionHide full description
Find a more useful speaker position by testing one change at a time. Speaker Positioning combines a measured 3D room view with acoustic measurements and a before-and-after comparison. SEE YOUR SETUP Mark both speakers and your listening position with the camera. View the room in 3D, rotate it, zoom in and switch to a top view. Read listening distances, wall clearances and proposed test moves directly in the scene. On a compatible LiDAR iPhone, scan walls, openings and simplified furniture. An optional second pass captures coloured surfaces. Switch between the clean measurement view and room colours. Without LiDAR, define the room footprint manually. TEST A CHANGE Connect your stereo system, measure at the listening position, then try one change. Measure again with the same volume, microphone position and signal path. Compare the left/right arrival-time difference, both bass-response shapes and changes in position. The app explains when two measurements cannot safely be compared. KEEP THE RESULT Save measurements and their room views locally. Revisit the comparison before deciding whether to keep the change. Speaker-model and subwoofer guidance help you plan further tests. FREE FEATURES • Guided sound, camera and combined workflows • 3D room view with useful dimensions and test positions • LiDAR room and colour capture on supported iPhones • Acoustic measurement, saved results and before-and-after comparison PRO — ONE-TIME PURCHASE • External measurement microphone with calibration-file import • Wired line output and loopback latency calibration • Impulse-response WAV and frequency-response export for REW IMPORTANT Camera dimensions and test positions are approximate. Coloured surfaces are not a photorealistic digital twin; hidden areas, glass and mirrors can leave gaps. Acoustic arrival times can include channel-processing delays. A smaller left/right difference alone does not guarantee better sound. Use repeat measurements and your listening impression to decide. Absolute acoustic distances require a valid latency calibration. An iPhone and a connected stereo system are needed for acoustic assessment. The iPhone-only playback option is a function test. Start at a moderate volume. No account, advertising or tracking. Measurement and room data are processed and saved on your device; you choose whether to share exports.

Verdict
The clearest difference is price: Speaker Positioning at Free against RE's $4.99. Speaker Positioning also leads on update cadence (every 2 weeks vs every 3 months). RE's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On ads there is nothing between them.
