Selcall Selective Calling Tone vs SoundMeter X

SelCall generates Selective Calling Tones. Select your tone type from the extensive selection of available modes, then touch the button for each tone you wish to send. You can even queue up tones and have them sent in a burst, if you wish. The following tone types can be generated: DTMF CCIR1 CCIR7 PCCIR EIA EEA CCITT EURO NATEL VDEW MODAT ZVEI1 ZVEI2 ZVEI3 PZVEI DZVEI PDZVEI ICAO ICAO SELCALL 32 CTCSS CODAN Touch the button on the upper right corner to get a list of SelCall tone modes, and select the mode you wish to use. Then touch the button for each tone you wish to generate. If you turn the switch off, you can queue up several tones (they will be displayed to the left of the switch) and then turn the switch back on to play them. Any tones that you played by turning the switch on can be repeated by tapping the RPT/Repeat button. You can also store commonly used tone sequences. Tap on the Mem button to bring of the list of memory entries, which will by empty at first. To add an entry, tap the Edit button, then the green plus sign to add an entry, which will get a default name of Untitled. Tap Done, then tap on the Untitled entry to edit it. You can change the name, as well as the tone keys to be sent. To send an entry, tap the send button. It will be sent (or stored in the buffer if the switch is off). It will also be placed in the repeat buffer, so you can tap RPT/Repeat to re-send it. The duration of tones and gap between them can be customized for most modes. Enter the values in milliseconds. The maximum allowed values are 500 milliseconds. In CTCSS mode, touch the button for the tone that you wish to continuously generate. There is a switch which turns the tone on and off, and when on, the tone will continuously play, even when you switch to another tone mode, so you can combine CTCSS with other tone modes. In CODAN mode, adjust the center frequency if necessary, select the priority of the message, and dial in the ID to call, and your ID. Then tap Send. Sequence mode allows you to create sequences of arbitrary tones. First, you will see a list of your sequences. You can use Edit to add additional sequences, delete a sequence, or re-arrange them. Three sample tone sequences are created for you, as examples. To rename a sequence, tap on it and edit the text. To edit to send a sequence, tap on the disclosure indicator at the extreme right. Each sequence is a set of lines, each of which has two numbers. The first is the frequency of the tone in Hertz, the second is the duration of the tone in milliseconds. One second is 1,000 milliseconds. Do not put an additional space between the numbers, after them, before them, or use any other characters, or the sequence will not correctly play. You can play two tones at the same time, in that case, three numbers must be entered on each line, the first two are the tone frequencies, the third is the duration. The first sample sequence, Seq 1, sends eight tones. The first is 1200 Hz for 550 milliseconds, then there are six more tones: 1100, 1000, 1100, 1000, 1100, 1000 Hz, each 200 milliseconds. Then a final tone of 1500 Hz for 350 milliseconds. To play a sequence, tap Send. To edit a line, tap on it and edit the text. You need a single space between the frequency and length. You can use Edit to add additional lines, delete a line, or re-arrange them.

SoundMeter X turns your iPhone or iPad into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, stereo signal generator, multi-channel data recorder, and real-time whole or 1/3 octave band spectrum analyzer (subscription or perpetual license required for most features--14-day free trial available). Input signals can be acquired from any available audio input path. Sensitivity calibration can also be performed for any audio input device and/or input channel. Direct hardware support (automatic sensitivity calibration, based on factory-defined values) for The Modal Shop’s 2-channel 485B39 USB-ICP interface and miniDSP’s UMIK-1, UMIK-2, and EARS microphones. In addition to real-time sound level measurements, SoundMeter can stream raw sound data to audio files, and store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device. SoundMeter may be downloaded for free from the App Store. Additional tools and features are offered via in-app purchase. The SoundMeter Pro subscription includes: - User-defined custom metadata in saved audio and data files - Level MeterLp, Leq, Lx sound levels -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. -- Event notifications - Max Levels Meter -- Traffic-light-style meters make it easy to monitor 2 separate sound level thresholds in 2 independent user-defined frequency bands. -- Define lower (warning) and higher (limit) sound level thresholds for overall (full audio band) levels as well as for individual octave frequency bands. -- Store user-defined thresholds in files for later recall. - Noise Dosimeter -- 8-hour Noise Dose, Projected Dose, TWA calculations -- Criterion Levels: 80, 85, 90 dB -- Exchange Rates: 3, 4, 5 dB -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Real-time Octave Spectrum Analyzer (RTA) -- Lp, Leq, Lx sound levels -- Supports whole or 1/3-octave frequency bands -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- NC, RNC, and NR references curves, NC, SIL, and NR values -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Multi-channel Data Recorder -- Supports up to 8 channels -- Live monitoring of recorded data -- Metadata (including calibrated sensitivity) embedded in audio file (AIF, CAF, WAV), optionally saved in separate data file - Stereo Signal Generator -- Left and right outputs assigned to arbitrary hardware output channels -- Random and pseudorandom (periodic) noise sequences with white or pink spectrum -- Linear and logarithmic frequency sweeps -- Dual periodic waveforms with arbitrary frequency and phase difference - MultiTool -- Powerful data monitoring and project management (Add 2-6 subtools, depending on screen size, and save configurations for easy recall at a later time.) The SignalScope X Pro Tool Set subscription can be shared between SoundMeter X and SignalScope X. It unlocks all tools and features of the SoundMeter Pro subscription in SoundMeter X and all tools and features of the Pro Tool Set subscription in SignalScope X (iCloud login required).
