Ultrasonic Analyzer vs SoundLab

Ultrasonic Analyzer is a real-time spectrum, spectrogram, oscilloscope, and octave RTA analyzer for your iPhone or iPad. It provides a visual representation of ultrasounds using a sampling rate of up to 384kHz**. You can listen to transposed ultrasounds* and analyze them in real time. For sounds that are normally inaudible, a slowed-down playback option is also available. Ultrasonic Analyzer can be used to analyze the calls of various animals (e.g., bats, dolphins), measure the frequency response of high-end audio equipment, or evaluate ultrasonic sensors. Additionally, it allows you to analyze short imported audio files within a spectrogram context. Features - Sampling rates: 44.1kHz, 48kHz, 96kHz, 192kHz, 200kHz, 250kHz, 384kHz** - Real-time transposed ultrasound listening during recording* - Spectrogram analyzer: Color and black & white modes - Spectrum analyzer - Oscilloscope (full FFT window size) - Octave RTA analyzer: Bands – full, 1/3, 1/6, 1/12 (RMS values) - Max/min Octave RTA values - dBFS Meter - Fast real-time response - Adjustable spectrogram frequency resolution - Configurable time interval between FFT computations, with values as low as 1ms or even lower - Fast Fourier Transform (FFT) - FFT window sizes: 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536 - Recording trigger: Automatically triggers based on specified frequency bands - Zoom and pan capabilities for all charts - Measurement tools available in all charts - Playback analysis - Transposition during playback - Slow-down playback: Transpose octaves down for easier analysis - Picture-in-Picture (PIP) mode: Allows simultaneous spectrogram analysis with a secondary chart (Octave RTA, Spectrum, or Oscilloscope) - Audio input support: Built-in microphone, external microphone (via USB camera adapter or iPhone/iPad dock connector – Core Audio compliant devices) - Sharing options: Share charts and audio recordings via email, social networks, or clipboard - Exporting capabilities: Save audio recordings (WAV) and image charts (PNG) to iOS Document Browser - Audio file import: Load short audio files from other apps or the iOS Document Browser - Supported audio formats: WAV, CAF, AAC, MP3 - Automatic sample rate conversion for imported files - Frequency scale options: Linear and logarithmic - Amplitude scale options: Linear and logarithmic (dBFS) - dBFS Meter weighting: dBZ (linear) - Adjustable spectrogram length (dependent on resolution settings) Tested with (via USB adapter): - Dodotronic Ultramic200K, Ultramic250K, Ultramic384K - Pettersson M500-384 - Avisoft UltraSoundGate 116Un Make sure you are using the latest iOS update. *Requires an external microphone with ultrasonic capabilities connected via a USB adapter. **Real-time analysis at a 96kHz sample rate or higher is only possible with an external USB microphone. Alternatively, you can import files recorded on an external device for non-real-time analysis.

Bringing desktop-grade audio editing, recording, and on-device AI together, SoundLab is a powerful sound editor that lets you edit audio, clean up speech, separate vocals, and mix up to 16 tracks. SoundLab is more than an audio editor. It is built for the ideas, quick edits, and unexpected creative needs that come up during music and podcast production, so you can start creating anytime, anywhere on your iPhone or iPad. We won't claim SoundLab replaces a desktop DAW. But it is a serious mobile production tool for the moment the idea arrives and you don't want to open a computer — or wait thirty seconds for a desktop DAW to launch. Precise Multitrack Audio Editor • Mix up to 16 tracks with gain, pan, mute, and reordering. • Copy, cut, paste, trim, insert, replace, split, duplicate, join, move, and more—with unlimited undo/redo. • Zoom smoothly for millisecond-level selections. • Loop any range while you work. • Draw non-destructive volume curves for fades and ducking. • Record overdubs directly into your project while monitoring playback. AI Vocal Separator & Vocal Remover Separate vocals and instrumentals, create acapellas, or make backing tracks with the vocal remover. Karaoke Mode preserves fuller accompaniment. AI runs locally: no uploads or server queue. AI Stem Separator Split into four stems—vocals, drums, bass, other—or six with guitar and piano. Preview and balance parts, then export a mix or individual stems. AI Noise Reducer & Audio Enhancer Use AI Noise Reducer on recordings or AI Noise Suppression on selected audio. EQ, compression, de-essing, normalization, amplification, and Bass Boost provide enhancement for voice and music. 25+ Selection-Based Effects Apply 25+ effects to any waveform range, including AI separation and noise suppression, 10-band EQ, Reverb Pro, Tape Delay, Compressor, Change Pitch/Tempo, Fade In/Out, Phaser, Reverse, Silence Remover, and more. Master Effects Master Effects run in real time on the mix bus. Adjust tempo, pitch, reverb, and EQ while previewing, then export alternate versions without changing tracks or clips. Audio Recorder • Quick Recorder: Capture ideas with your chosen input device. • Recording Studio: Monitor your mic, set input gain, use a limiter and reverb, and record over a backing track—with or without it in the saved mix. • Use compatible external microphones and audio interfaces recognized by iOS. Import, Create & Organize • Import from Files, Music Library, other apps, or Wi-Fi; extract audio from video. • Convert text to speech and add, insert, or replace audio in your project. • Sync audio with iCloud; archive and restore projects through iCloud, USB drives, or external storage. • Use Video Composer to mix audio with video and create soundtrack videos. Flexible Export Export AAC, ALAC, MP3, FLAC, or WAV with selectable channels and sample rates, plus high-bitrate and lossless options. Add metadata and cover art in supported formats. Save to Files or iCloud, share, or export a ringtone. SoundLab is perfect for: • Music lovers and independent creators • Podcast and voice-over producers • Music students and teachers • Especially for users who are familiar with Audacity or Audition SoundLab Pro SoundLab Pro unlocks all Pro features.
