Boost your creativity and transcribe your guitar songs into sheet music with Tabs and Chords. All the features of Guitar2Tabs: » Transcribe solo guitar recordings to sheet music » Transcribe solo guitar MP3 files to sheet music » View the transcribed music as score with tabs and chords » Playback the sheet music and listen to the result » Download sheet as PDF, MIDI, Guitar Pro 5 or MusicXML » Share your compositions with your friends HOW DOES IT WORK? Once your music piece is uploaded, our artificial intelligence powered transcriber processes it to generate a sheet music based on what it hears. When the processing is finished, you can view the final sheet and export it in different outputs - a Midi file, a PDF engraved sheet, a Guitar Pro 5 file and a MusicXML digital note sheet. It has never been easier to convert guitar songs to sheet music! WHAT THIS APP DOESN'T OFFER » Separation of multiple instruments: The note recognition can't separate multiple instruments from your guitar sound. If you record multiple instruments playing simultaneously you will get bad transcription results! As the name says, Guitar2Tabs will only work with guitar sound recordings. » Live note recognition: This app is not able to show you live note recognition results. Instead, it will take some time to perform the frequency analysis and shows you the final sheet music. » 100% match percentage: This app won't detect 100% of the played notes and there will also be wrong detections. But depending on the quality of the input signal, it will give you more than useful sheet! REQUIREMENTS » Internet: active internet connection for server connectivity » Microphone » An awesome guitar SUMMARY Transcribe music recordings from your microphone to sheet music. With Guitar2Tabs you can create on-the-go recordings of your guitar performance. Those are uploaded to your personal songbook and transcribed to score. Musical note recognition for guitar has never been so easy! CONTACT US We're always happy to hear from you. No matter what comes to your mind, we want to hear it. Would you like another feature?

SonoSpec turns your iPhone or iPad microphone into a beautiful real-time audio spectrum analyzer. Built for car-audio tuning, room acoustics, HVAC and machinery noise hunting, speaker testing, and anyone who wants to SEE what they're hearing. FOUR VIEWS, ONE INSTRUMENT • Spectrum — live FFT trace with peak hold and a log-frequency grid • Waterfall — scrolling spectrogram that makes tones, sweeps and rattles obvious • Split — spectrum and waterfall together • Octave — 31-band 1/3-octave RTA bars MEASUREMENT-GRADE DETAILS • FFT sizes from 2,048 to 16,384 points (5.9 Hz resolution at 48 kHz) • A, C and Z weighting curves computed per the IEC 61672 formulas • Exact base-10 1/3-octave bands per the IEC 61260 definitions • Peak-hold trace with slow decay, pause/hold, and a drag cursor that reads out the exact frequency and level under your finger • Levels in dBFS with a proper full-scale sine reference and window-bandwidth (ENBW) correction — the numbers mean something BUILT-IN SIGNAL GENERATOR • Pink noise, white noise, sine, log sweep and warble tones — the source half of the RTA workflow • Feed the system under test by cable or USB and watch the response live TARGET CURVES • Overlay a house curve — flat, −3 dB/oct tilt, or a bass-lifted car target — on the live spectrum • Auto-fit positioning: the shape snaps to your measurement, no fiddling SNAPSHOTS & EXPORT • Freeze a measurement and recall it as a ghost overlay for before/after comparison • Share a publication-ready image or CSV with a full metadata header — FFT size, window, weighting — so your data still means something later TUNED TO FEEL LIKE HARDWARE Rendering runs on a dedicated Metal graphics path at the full analysis rate, with a phosphor-and-ember instrument look that's readable at arm's length. On iPad it fills the screen and adapts to Split View and Stage Manager windows. PRIVATE BY CONSTRUCTION Audio is analyzed on-device and never recorded, stored, or transmitted. SonoSpec has no accounts, no ads, no analytics — the app cannot even access the network. One-time purchase. No subscriptions.
