Expandable memory

With the ICD-PX333D, you don't have to worry about running out of recording space. The recorder has 4GB of built-in memory. That's enough for 178 hours of basic-quality recordings, or 6 hours of CD-quality audio. But if you need more, just insert a microSD card into the player and keep recording.

Easy on-the-go recording

The ICD-PX333D features Scene Select to take the guesswork out of recording. Simply select what you want to record, such as lectures, music, or personal memos, and Scene Select automatically adjusts the recording levels for you. And the intelligent noise cut feature further improves recordings made under less-than-ideal circumstances. The voice-activated mode lets you make convenient, hands-free recordings.

Playback options

Use the built-in speaker for playback, or plug in your headphones for more discreet listening. The recorder can deliver up to 96 hours of operation with two “AAA” batteries (included).

It has a built-in mono microphone, mono speaker, and jacks for an external microphone and headphones. The PX333D operates on two "AAA" batteries (supplied). Included with the recorder is the Dragon NaturallySpeaking software on DVD-ROM.

LCD Display: The PX333D features a 15/16" x 1-1/8" monochrome LCD display which indicates recording and playback information. The recorder will display the elapsed or remaining recording time in hours, minutes, and seconds. When not recording, the current time can be displayed.

Date and Time: The recorder features a built-in clock. If you have set the time and date, information as to when a sound file was recorded is stored automatically with that file. In addition, you can set an alarm and start playback of a selected file at a specified time.

Built-in Microphone: The unit features a built-in monaural microphone on the top of the recorder. You can set the microphone sensitivity to High or Low. In addition to the built-in microphone, the recorder also has a 3.5mm external microphone input. Stereo recording is possible when using an external microphone.

The unit has 5 pre-programmed folders (400 maximum), and up to 199 files per folder (or a maximum of 4074 files). Because a portion of the memory is used for system management and/or application files, available capacity is approximately 3.6 GB.

Dragon NaturallySpeaking: The ICD-PX333D includes the Dragon NaturallySpeaking speech recognition software (Recorder Edition 12.0) on DVD-ROM. You can capture your thoughts and ideas, or record a speech or lecture on the recorder, and the speech-to-text software will translate the audio to words on the page. Dragon NaturallySpeaking is compatible with Windows XP (SP3), Vista (SP2), Windows 7, and Windows 8.

Sound Organizer: The unit features built-in Sound Organizer editing software. When you connect the recorder, you can install the software on your computer. Sound Organizer is compatible with Windows XP (SP3), Vista (SP2), Windows 7, and Windows 8.

Recording Features

Recording Format: The ICD-PX333D records audio files in MP3 format in four recording modes at bit rates of 8 kbps to 192 kbps. Lower bit rates provide longer recording times while higher bit rates offer better quality recordings. The selectable recording modes are as follows:

Recording Mode Recording Bit Rate/Sampling Frequency Frequency Response Maximum Recording Time

SHQ: Super High Quality 192 kbps

LP: Long Play 8 kbps
100Hz - 3500Hz 1073 hours 96 hours

VOR Function: The VOR (Voice-Operated Recording) function makes the digital voice recorder start recording when the recorder detects sound, and pause when no sound is heard, eliminate recording during soundless periods.

Intelligent Noise Cut: Sony's Intelligent Noise Cut feature significantly reduces ambient noise during recording for clearer playback.

Scene Select: You can select a pre-determined recording mode with the push of the Scene Select button. You can choose from Meeting, Voice Notes, Interview, Lecture, and Audio In, to optimize the recording settings for each type of scene.

Edit and Playback Functions

Overwrite and Add Functions: The PX333D allows you to correct dictation in playback and add a recording after the original recording. Added recording will be placed after the current file, and will be counted as a part of the file.

Divide: In the stop mode, you can divide a file into two parts, with the new file number being added to the newer part of the divided file.

Erase: You can erase your recorded messages one by one, or all messages in a folder at one time.

Track Mark: You can place up to 98 track marks for each file to assist you in finding an exact spot in your recording.

Protect Files: To prevent a file from being accidentally erased or edited, you can protect an important file. When a file is protected, it is regarded as a read-only file. Protection can be released, if desired.

Built-In Speaker and Headphones: The PX333D features a built-in, 1-1/8" diameter speaker for listening back to your recordings. The recorder also features a 3.5mm headphone output.

Easy Search: You can go forward for approximately 10 seconds or back for approximately 3 seconds to locate a desired point in a long recording.

A-B Repeat: You can place marks at the beginning and the ending of a recorded passage for repeated playback. This constant repetition feature can be used for language learning.
