Speaker Positioning vs Morlet

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.

Morlet shows the sound around you as a live, scrolling picture of frequency over time. Sing, play, whistle or just listen to a room, and watch notes, harmonics, rhythm and noise appear as they happen. TWO WAYS TO SEE SOUND • Spectrum: a fast Fourier transform with up to 288 rows and 8,192-sample frequency detail, on a log or linear axis. • Wavelet: a continuous Morlet scalogram with up to 48 scales per octave, giving low notes precise pitch and high sounds precise timing. Mexican Hat, Haar and Daubechies 8 wavelets are included too. OPEN ANY AUDIO • Play songs, voice memos and recordings from Files, or share audio to Morlet from other apps, with the graph scrolling in sync and a slider to jump around. READ ANY MOMENT • Tap or drag on the graph to read the frequency, nearest note with cents, level and time at that point. • Freeze the picture to study a moment while the microphone keeps running. • A pitch line traces the note across the graph with markers at its harmonics, and the tuner shows the note and cents. • A spectrum curve above the graph shows the current spectrum with averaging and peak hold, or octave and third-octave bars. • Save any view as an image to share. TUNE IT TO WHAT YOU HEAR • One-tap setups for music and singing, speech, drums, hum and machinery, and birdsong. • Set the lowest and highest frequency to put every row where you need it. • Choose the window shape and A or C frequency weighting, and generate sine, triangle, square and sawtooth tones or a full-range sweep. • Adjust frequency detail, time overlap, brightness and contrast. MAKE IT YOURS • A lab-notebook design in ink on white, or matte black for night use. • Choose your accent color and graph colors, including Ink, Sepia, Inferno, Grayscale and fully custom colors. • A built-in guide explains what each setting is for. RECORD AND EXPORT • Record sessions and share them as uncompressed WAV audio, CSV analysis data in decibels, and JSON metadata describing the settings used. • Recordings stay on your device until you share them. ON IPAD • A larger graph with every analysis setting open beside it, in portrait or landscape. PRIVATE BY DESIGN Morlet has no accounts, ads, tracking or in-app purchases, and collects no data. Audio is analyzed on your device and never leaves it unless you share a recording. Good for musicians, singers, sound designers, students, teachers, audio engineers, bird lovers, and anyone curious about what they are hearing.
