Ver 1.40 * You are able to send your recorded-audio-files by e-mail (large-volume mail server such as iCloud Drop Mail). * You are able to send your text-log by e-mail. * Carrier Detect processing is able to highly precise decoding without noise. (New carrier detection system) * New-synchronize-system are able to improve precision. * After telephone call, the VBC can be resumed to recording or decoding by automatically. * Calibration mode is changed to be flat by setting default button. * SECoreTextView was changed to v0.8.5.

All rights reserved. bugfix * Carrier detection judgement is not carrier, but it is indicate blank only. * Only first installing default setting is not correct. (A new synchronization system wasn't functioning.) * Decoding center processing is corrected. The signal corrugated detection on the filter boundary was made severe. iOS 8.0/after is available from this version. (iOS 5.1-7.* doesn't available.)

You need update the VBC decoder to Ver 1.31 which is on iOS 9.* The VBC decoder 1.21 does not decode on iOS 9.* Ver 1.31 *You can not use help, because web access API changed to able to https only on iOS9.* Now, you can use help files.

You need update the VBC decoder Ver 1.30 which is on iOS 9.* The VBC decoder 1.21 does not decode on iOS 9.* Ver 1.30 *Adding AGC Auto Gain Control fast-slow setting. *Because data size of voice input API changed on iOS9.* , the VBC decorder can not decoded. So I changed interface program.

Ver 1.21 *I changed subroutine using kishikawa katsumi's PETextView for scrolling-problems on iOS8.*. PETextView Created by kishikawa katsumi on 2013/04/20. Copyright (c) 2013 kishikawa katsumi. All rights reserved. *Adding PAUSE/RUN button. The PAUSE button is suspending decoding temporarily. The RUN button is start decoding. (muku-kiri san request) *Detaching the backlog-erase-confirmation at starting of VBC. Attaching the backlog-erase-confirmation, if long-size-backlog makes low-decoding-speed. (muku-kiri san request) *Detaching strange character around the Frequency indicator on iOS7.*. *The backlog, which is for e-mail, may be left bigger size if possible. * The back-scroll buffer is limited to 2000-6000 characters (by the size of the character shape) . This buffer size will not slow down decoding-speed. *Scrolling-position by touch is not change until new-signals-detection. *Setting page is no space. Attaching new swipe setting pages.

New Functions - Automatic fit iPhone5 screen size. - Audio frequency characteristic measurement function. - Audio frequency characteristic calibration function. Speaker's/Head phone's audio frequency characteristic calibration are able to memorized and automatic calibration audio level for decoding. - Decoding center frequency can be set up and decoding range can be set up from the center ±125 / 250/500 Hz / all range. - End button demiss(apple's request). - Decoding　character can be selected capital/small letters. - normal/dxmode -> level slider button. - Font sizes can be selected small/mid/large sizes. - Change tool bar design. - Add new wpm synchronize mode. bugfix - Abnormal end when the continue-long-sound's frequency is changed. - Abnormal end when the log-text is cleared.

Letter-size select function added. CW carrier detect ability enhanced. Number recognize ability enhanced. Space-mark-detecting continues recoding time to be long. It makes no delay scrolling Morse code and sound wave screen that the back-scrolling 500 characters limit. All log-text could be send by e-mail. If you did not finish by finish button, you can remain a past log. bug-fixed) Corresponding the memory increase bug of iOS text scrolling. Connected-Morse-code recogunized feature's sometime makes same-letters. Manual frequence mode do not work.
