Functions
Dictation Correction overwrites the file, during the playback, so to replace any incorrect information. Really useful and interesting. In addition, the digital pitch control, the A-B Repeat, substantially a looper, the Voice Operated Recording, that stops the device during pauses and starts automatically when detects a new signal, and the alarm.
The quality/price ratio is very valid
The ICD-PX820 is a good Sony product. At an excellent price, approximately 65 Euros, it provides all the necessary to make a good job. The lack of a memory slot is not a great problem. 2 GB of flash memory allow an excellent autonomy.
