Improvements in the Sparky + USB Recorder

1.Up until now, Primos and Sparkys both recorded a telephone conversation by recording the handset speaker signal only. That signal was usually sufficient to record both sides of the telephone conversation because there was sufficient side tone in the telephone set or phone system to record the local caller. On some systems, however, the side tone level is very low resulting in the recorded level of the local caller being very low. Sparky + remedies this problem by adding a second record path that records the handset microphone signal for the local caller. This path has an adjustable record volume control so that the local caller and remote caller can be recorded at the same level. The volume control is located in the user interface under the device control tab (see picture below), and is called Sparky + Gain. Note that the gain control only appears for Sparky +. The default value for Sparky + gain is 0; and it can be adjusted anywhere between 0 and 255. It should only be adjusted if the low side tone problem exists as described above. Once set to a satisfactory level, there should be no need to re-adjust it because the system will remember and recall the setting every time the recorder interface is started.

2.Playback level to the remote caller has been increased in hardware.

3.In version 2.07 of the USB recorder software, there is also an adjustable playback level control in the upper right corner of the GUI.

This allows for a + or - 20 db of playback level adjustment (see picture below).
