Analysis position fine designation function
Analysis position fine designation function (analysis mode)
Only in the case of Wave file performance, since it operates so that the Wave / Spectrum display also follows the change of the position of the track bar during pause, Wave waveform and Spectrum can be observed.
Furthermore, only in that case an elongated button appearing on the track bar By pressing the " position specification window " , You can specify exactly any position represented by the number of samples or elapsed time.
*The track bar in the main window and the movement operation in the position designation window are linked with each other, so change the position You do not mind.
You can also resume playing Wave files from that position.
Close button * or close button again I can.
(It temporarily closes when resuming the performance of the wave file or stopping it)
Position selection window
At the far left, the current wave position is displayed in terms of the number of samples and the number of seconds since the beginning of the file, and to the right of it the last position of the file (all file sizes) is displayed as well.
- Position move button
Two buttons move back and forward , button to the end - with you can move the current position.
*The left and right arrow buttons repeat as long as you press and hold.
*When pressing the Shift key, the left and right arrow button temporarily moves the amount of movement It can be multiplied by 10.
Move to the end button Please be aware that " end " is actually all zeros beyond the end of the file.
From there, only the portion returned by the left arrow button is analyzed from the left to the analysis window " will come back "
For example, after moving to the end, if only one sample is returned, only the last sample data of the original file is FFTed as the leftmost head data (all other zeros are all zeros) Become.
- movement amount
Set the amount of movement when pressing left and right arrow buttons.
"Number of samples", or "seconds" You can specify with the combo box the amount of each movement.
*By writing not only the values ??in the list in the combo box but also the direct value arbitrary value.
- Short play button
When you press the button, you can play the sound of the current position for about 0.1 seconds.
Every time you press it, the On / Off state repeats, each time a sound comes out.
Press and hold it to repeat.
If you leave it pressed while it is on, you will hear the sound at that position even when you press the position move button to move.
With the checked, the sound of the length of the current FFT sample data (one frame) is played at will.
Note:However, this is a function only when the driver is MME.
If you think that the way the sound is repeated when repeating is not smooth, improving the resolution of timer / pause may improve it.
(See the Settings Dialog - Other Tab - Timer / Hibernation Resolution
Note:When using some devices with ASIO 4ALL, it can take quite some time (about 0.3 seconds? There is.
 Pressing the Add button remembers the current position as a marker and adds it to the list with sample value and time.
The label will automatically be Marker 1, 2 ....
 By selecting a marker on the list and double clicking you can move to the position of the stored marker.
 Select a marker in the list and press Delete button to delete that marker.
Pressing theDeletebutton while holding down the shift key will delete all markers.
 You can change the name (label) of the marker by pressing the Rename button.
 If you made any changes, you can write the marker information to a file by pressing the Write button.
If there is cue chunk in the original file, if there is not, add cue chunk to the end of the file and write it.
Please understand that the file is changed directly.
(Of course, other original data such as waveform data is not changed.)
Even after making some changes, the list is reset without any warning whether or not to write to another file at the time of opening another file.
Please write it in a file if necessary.
* You can display many ranges in the list part by expanding the window in the vertical direction.
When the name change button is pressed
- Display function of cue chunk contents of Wave file
When the Wave file contains cue chunk , its contents are displayed in the list as shown below and
It will be available as a marker.
If it also contains LIST adtl chunk , it will also display a label (labl).
If the label display garbled, try unchecking "Show " in UTF_8 ". (Indicated by SHIFT-JIS)
* Tip 1
If you want to move to a fixed time position such as the second from the beginning of the file, once you move it to the top with the button to the top, enter the time (or number of samples) there in the movement amount combo box By pressing the right arrow move button, it is possible.
* Hint 2
In Spectrum 3D display, each time the position is changed, one by one The graph of Spectrum increases as it shifts.
Therefore, if you use this function well, you can use multiple You can display Spectrum together in 3D.
If you want to erase the entire 3D display, you can erase it by changing the size of the window from the 3D display to the normal display once and then returning to the 3D display again, or keeping the 3D display. (It's a little troublesome (^ ^ ;;)
You can move the window frame only a few times.
*Even when the format of the Wave file is an unsupported format of the playback device, or when there is no sound device at all from the beginning, Analysis position You can analyze using the fine designation function.
In this case, if you press the play button after opening the file, you can not play it for those reasons A message box with a message saying "It will be displayed every time.
If this is troublesome, when you press the play button, if you start from the beginning in the pause state by pressing the play button while holding down the Shift key, the message box above is not displayed .
