Generator vs BFM

A high-quality audio Signal Generator for the iPhone. Now you can have a professional grade signal generator for your iPhone. Create sine waves, square waves, white noise, and pink noise. Don't let the well-worn look of this classic audio must-have fool you, Generator is accurate, reliable, precise, and clean. ** NEW! Now supports remote control over WiFi from our AudioTools app. Connect an iOS device running Generator to your audio system, link to AudioTools on another device, and control Generator from AudioTools as you are free to move around. Requires that both devices be on the same LAN. In sine and square wave mode, you can select between 20Hz and 20kHz using a controller that has three resolutions: octave, 1/3 octave, and fine. Frequency selection is controlled by smooth-gliding interlocking control wheels. Just spin to change frequency, by octaves, 1/3 octaves, or select fine mode to sweep through any value. *** NEW: Tap the frequency screen to pop up a keyboard so that you can enter any exact frequency. *** NEW: Tap the Wobble button to create a warble-tone signal for acoustics work. Doubles as an emergency siren! When you are generating pink noise and white noise, you can select full band (20Hz-20kHz), or octave band limited noise for acoustical testing. All waveforms are laboratory accurate, and use ANSI / IEC spec filters where appropriate. The frequency sweeps smoothly, with no glitches. The mute is soft, to prevent loud impulses when mute or turning on a lower-frequency signal. This signal can be sent to both channels (stereo), just the right or left channel, or the right channel output phase can be inverted for pseudo-balanced mode. This mode can be used with our iPhone Balanced Cable Adapter to get a balanced signal from your iPhone. See our web site for more information. On an iPhone 3G, we have measured distortion at .006% THD at 1000Hz at full volume (+6.5dBu balanced). See our web site for more level details. Note that digital square waves suffer from aliasing problems, and sound very strange above about 1500Hz. Future versions will have options to select different skins. Check out out other great professional-grade audio and acoustics apps: SPL, the iPhone professional-grade sound level meter, SPL Graph, for recording SPL over time, RTA, a 1/3 octave real time analyzer, FFT, for detailed audio analysis, ETC, the iPhone energy-time curve and decay app, RT60, for automated octave-band decay measurement, and Speaker Pop, the speaker polarity tester.

BFM or Big F*ing Meters is a macOS, Windows, and soon to be iOS compatible Metering plug-in designed exactly how the name sounds... really f*ing big. With the main goal of readability we wanted to bring a meter that you can see from across the studio and keep your records clip-free. BFM currently offers 6 Modes with RMS, LUFs, Peak, and Peak Hold values, to give you a variety of views to keep your signal under control. The Text, Bars, Waves, VU Meters, Spectrum, & Time  let you decide how you want to keep track of your signal with multiple fonts/formats to view them in. Text gives you a quick look at just the values easy to see from across the room. This view offers the most values with RMS, Peak, Peak Hold, and LUFs (Short Term & Momentary with Maximum values and LUFS range) values available. Controllable sensitivity & peak hold time for all pages. Reset Peak Hold with a click off the value. Bar offers a more traditional meter for seeing the range of values showing RMS, Peak, Peak Hold, and LUFS. Correlation & Balance meters included to set your stereo image and phase response. Peak Hold resets on value click. Sensitivity changes on bar click. LUFS readings select on click. Included reference points for -24 (EBU), -16 (Apple Music), & -7 as a suggested maximum for most genres. Wave view gives you a look at your waveform after your channel effects with the ability to quickly mark in dB where you want to see your signals peak. To freeze click the waveform. To reset Peak Hold click the value. VU Meter Designed for a quick look at your overall levels. Featuring controllable Attack, Release, Minimum, and Maximum value control. Left/Right, Mid/Side, PPM, and LUFS options available. Click VU to enter dark mode. Spectrum is a simplified frequency spectrum view with 3 quality modes. Great for getting an overall look at where your frequencies are when mixing or editing. Tap to freeze and inspect. There is also the PEAK value displayed on this page. To reset Peak Hold click the value.
