Audio Function Generator vs Sweep

This is the highly recommended and praised Function Generator App - an amazingly great and powerful tone generator. Enriched with a vast amount of features yet it is extremely intuitive and designed for simplicity. Get to know this great App now! It is very well maintained and has received considerable upgrades over the past years. So, … what can you do with this App? • PLAY TEST TONES Sine, Rectangular, Triangular and Sawtooth. • PLAY FREQUENCY SWEEP TEST TONES in both directions (minimum to maximum frequency and maximum to minimum frequency). • PLAY VOLUME SWEEPS (from minimum to maximum volume). • Try the SWEEP REPEAT / WOBBLE function. • Try the MUSIC TONES PLAYBACK. • Experiment with the huge FINE TUNE SELECTON, PRESETS SELECTION! • Or create your own CUSTOM PRESETS! • And SAVE an endless amount of CONFIGURATIONS (Frequency, Sweep, Noise) for later quick access and direct playback function. • Even play back different kinds of NOISE – White, Pink, Violet, Grey, Brown, Blue is also supported. The Function Generator is AMAZINGLY INTUITIVE and SIMPLE to use! AND THESE ARE THE ADVANCED SETTINGS/FEATURES (upgrade to PRO required): => Extending The Frequency Range (1Hz - 21kHz) => Extending The Sweep Times (0.1s - 600s) => Changing Min/Max Slider Frequency Ranges => Changing Max Sweep Time Slider Range => Changing Signal Amplitude => Enabling Of The Sweep Repeat / Wobble Function => Frequency Slider Setting to Linear or Logarithmic => Left/Right Channel Individual Selection => Permanently Saving Custom Presets => Saving Of Endless Number Of Audio Configurations => Phase Out Setting (custom phase shift of the generated signal) => BPM (Beats per Minute) Feature => Dual Function Generator => MultiTone Generator (playback of up to eight individual tones) => Background Theme Selection (Light/Dark) Check out the tutorial page: www.ee-toolkit.com/audio-function-generator

See how your speakers really sound. Sweep plays a log sweep through your speaker and plots its frequency response — measured from your listening position. No laptop, no audio interface, no mic stand. Just your iPhone or iPad, a calibrated mic, and a clear picture of what you're hearing. The untethered scout between full bench sessions — the fast check from your chair you'll actually run. A minute, not an afternoon. SWEEP. CAPTURE. COMPARE. • Sweep — tap once and a 20 Hz–20 kHz log sweep plays through your speaker (the Farina ESS method the bench tools use). • Capture — a calibrated measurement mic (Dayton iMM-6C, miniDSP UMIK-1/UMIK-2/EARS, Behringer ECM8000, or any REW .cal file) or your device's built-in mic records it, on-device math extracts the impulse response and plots the curve. • Compare — overlay up to 5 runs, each its own color, to see exactly what a change did. Measure, adjust, measure again. TWO WAYS IN No audiophile experience required. Tune My Receiver runs a guided measurement, then hands back actual settings — "Bass +5, Treble +8" — instead of a chart to interpret. A plain-language results tour walks through what it found, and Balance Speakers checks your channels match before you start. Measure Again starts a new before-and-after round without losing the first. Prefer the full picture? Everything above is one tap away, from the same library. ALSO IN THE APP • Scrub any frequency — drag the cursor; it snaps to peaks and troughs and reads frequency · dB right where you need it. Pinch to zoom into any band; hold near the edge to pan. • Target curves — overlay Harman Room, B&K, a tilt, or Room Gain as a dashed reference so you know what "good" looks like, not just what you measured. • Aim at what you listen to — pick a listening style (Bass-forward, Warm, Bright, and more) and Tune My Receiver's recommendation steers toward it, not just flat. • Average or Difference — power-average two or more captures (walk the room, average the seats) or compute A − B to see exactly what a change did, both as new measurements you can keep comparing. • Real smoothing, applied after the fact — every capture keeps its full resolution; change 1/24 to 1/3-octave anytime and every trace redraws, no re-measuring. • Set levels with confidence — a built-in test tone and live meter get your output where it should be before you measure. Each mic keeps its own calibration trim, so swapping mics never carries a stale correction along • Share your capture — export the chart as a labeled image card: color-coded traces, an optional cursor callout, one tap to send anywhere. From Tune My Receiver, the card carries your verdict and knob settings too. • Handoff to your Mac — pair once, and send a capture straight to Sweep for Mac's library: device to device, encrypted, no internet, no cable. Off by default; turn it on in Settings. • Undo delete — swipe away a measurement by mistake? Undo is right there for a few seconds. HONEST BY DESIGN Sweep shows relative frequency response — the shape you need to tune speaker DSP and EQ. A time-gate isolates the direct sound; the low end reflects your room, and the chart marks that region plainly. Results are only as calibrated as the mic file you import. Not an SPL meter, not a full bench replacement — it names its limits up front, so you can trust its strengths. PRIVATE BY DEFAULT Everything runs on your device. No account, no signup, no cloud, no tracking, no analytics SDK. Your measurements are processed entirely on your device. They go only where you send them — a paired Mac in the same room, or a file you share. Free. No in-app purchases, no account. Sweep is part of a family of focused instruments alongside Pull, Grip, Lean, and Level.
