History

V1.50 (2013/01/05)

  • Corresponds to WASAPI (Windows Audio Session API) . (Windows Vista SP1 or later)
    Exclusive mode exclusive (Both event drive mode and timer drive mode)
  • Corresponds to multichannel up to 8ch .
    It corresponds to multi channel Wave file (WAVEFORMATEXTENSIBLE format).
  • Add Wave 4. Add 2 more pairs Wave 5 ~ 8. (created up to 99 MHz)
  • Add pulse (+ -) to the waveform. Stop the operation OFF addition.
  • Add band limitation (addition synthesis, BLIT synthesis) to the periodic waveform of Wave 1, 5.
  • Change the sawtooth and triangle start position according to the band limit waveform. (From negative maximum value)
    (From the one sample of 0 for sawtooth wave only for addition synthesis)
  • In Wave 1 and 5, you can now rotate the mouse wheel to continuously change the frequency / cycle and amplitude (volume) , To the operability like the analog oscillator. (Change amount and change time can also be set)
  • Added pulse width modulation (PWM) to the modulation of Wave 1,
    Duty cycle can now be changed. (Other than sine wave, addition synthetic waveform))
  • Add Wave 5 to the modulation signal of Wave 1 . It became possible to select Wave 3 / Wave 5.
    Therefore, the user waveform (Wave 5) can also be used as a modulation signal.
  • Add frequency setting bar to Wave 1.
    Smooth frequency change and sweep with the knob of the track bar became possible. (Sweep speed can also be set)
    It is possible to change the frequency of Wave 5 synchronously while keeping an arbitrary ratio to the frequency of Wave 1.
  • Change registration of user waveform from right button to dedicated button.
  • Change handling of registration window and user waveform of user waveform .
    Output channel and modulation signal of Wave 1 (Wave 5 only) can be selected separately.
  • Add output filter function.
    Filter setting window which can easily change various parameters.
    Oversampling function.
    Filter characteristics can be changed in real time even during sound generation operation.

    Improvement
  • Improve internal processing of playback.
  • Improved waveform display .
    Change display sample number to same as internal buffer.
    Improve accuracy of graduation. Improve display rate.
    The waveform can be stopped and displayed when the display magnification is twice as wide as the horizontal magnification. (Trigger function)
  • Change the display window when pressing the available format button in Playback Device Setting Dialog .
    The window is displayed first and the currently checked place is displayed in real time.
    Also, from the display of S, M, etc., it changed to display with the number of the supported channel number.
    Enlarge usable format to 384 kHz.
    I separated the Info / Panel buttons respectively. (ASIO, WASAPI)
  • We recorded the version number in WG.INI and displayed the initial message + help when the version changed.
  • buffer change, FFT size change.
  • ASIO IASIOThiscallResolver changed.
  • The maximum 0 dB limit was eliminated by setting the amplitude value.
  • Change preset value of combo box. It corresponded to
  • theme.

    [Bug fix]
  • Fixed bug in waveform display when reading large user waveform.
  • Fixed size limit processing when changing window size.
  • Fixed line breaks of lines missing 10 data in text format file output.

V1.40 (Dec. 15, 2007)

  • Added user waveform generation function . (Modulation is AM, DSB only)
  • M series noise (MLS) added.
  • Add text format output (*. WGT).
  • Added up / down control for changing frequency and amplitude.
  • Optimized sample data length for FFT is supported up to 131072.
  • When setting it to 1/2 Fs or more, the background of the frequency setting combo box is made to be " red ".
  • Improvement of noise.
  • Improvement of each response at playback. (Buffer reset, buffer configuration change, waveform display update speed)
  • Improve the accuracy of the waveform when the frequency is high.
  • Fixed a bug in the scale on the horizontal axis of the waveform display, x 17 when it is 176400 s / s or more.
  • Fixed that sweep length could only be set in integer seconds. (3.5 seconds etc.)
  • Fixed that the output frequency did not follow when changing the sampling frequency when the unit of frequency setting was periodic.
  • Changed Help to HTML Help.
  • Changed the archive file to * .ZIP.

V1.31 (February 22, 2004)

  • Corresponds to drag & amp; drop of parameter file (*. WG).
  • By specifying the parameter file as the argument of the command line, it can be started with that setting (only setting change when activated), and automatic playback (with length specification) also enabled.
  • Fixed a bug that could not be started due to an error at the next startup when setting driver to DirectSound and finishing.
  • Fixed a bug that could not be used at all when Windows ME / 98/95 driver is MME.
    (I made WAVE_FORMAT_DIRECT possible to turn on / off with WG.INI)
  • Fixed a bug that could not handle resizing of title bar.
  • Fixed a bug that the free space became zero and writing was impossible when directly specifying the network drive at the time of file writing.

V1.30 (2003/10/04)

  • ASIO, DirectSound, and WAVE_FORMAT_EXTENSIBLE (2ch only) format compatible.
    (Significant remodeling of playback section)
  • Supports IEEE_FLOAT (32 bit floating point) format playback and wave file creation.
  • Conventional (at MME), WAVE_FORMAT_QUERY when displaying supported format list Changed to actually open once you were inquiring with.
    (For drivers reporting lies?) By double clicking on
  • compatible format list, we can change it to that format.
  • Changed to show the waveform display from the first startup.
  • Fixed a bug where the length of sweep was wrong length when changing sampling frequency.
    (The length setting is an integer only and the same as before)
  • Fixed a bug in waveform display and screen locking occurred.
  • Depending on the environment, avoiding occurrence of zero divide error when selecting wave mapper is avoided.
  • Other, minor modifications and changes.

V1.20 (2000/01/25)

  • Supports 24 bit, 32 bit format.
  • Added the playback device designation function and display format display function.
  • Changed to be able to set the number of seconds as a decimal value.
  • Corresponds to the number of samples for optimization for FFT up to 65536.
  • Fixed a bug that caused ZeroDivide error or general protection error when blank or small value in combo box was set when setting arbitrary sampling frequency.

V1.10 (February 28, 1999)

  • Addition of sweep function (frequency, amplitude, phase)
  • Added modulation function (AM, DSB, FM, PM)
  • Addition of gate function (tone burst)
  • sawtooth wave addition.
  • Add offset.
  • Added waveform display.
  • Added comment to parameter file.
  • The level indication can be displayed up to 0.1 dB.
