Sony ICD – PX 470 Overview.

The Sony ICD-PX470 is a digital voice recorder designed for capturing sounds and voices with superior clarity. Here are some of its key features:

USB Direct Connection: You can quickly transfer files to or from your computer by plugging the ICD-PX470 directly into a free USB port—no need for a separate USB cable.

Expandable Memory: The recorder comes with 4GB of built-in memory, allowing for a maximum recording time of approximately 59 hours and 35 minutes when recording in stereo at MP3 128kbps. Additionally, you can expand the memory capacity by using a micro SD card (up to 32GB), equivalent to over 536 hours of recording time at MP3 128kbps.

Calendar Search: Recordings are organized by date, making it easy to find specific files based on when they were made.

Transcription Playback: Reviewing recordings is simplified with the transcription playback mode. You can fast-forward, rewind, and create cue points to navigate through tracks.

Digital Pitch Control: Adjust the playback speed to listen more closely to what’s being said. This feature is useful for transcribing interviews or lectures.

Low Cut Filter: Eliminate unwanted low-frequency background noise during recording. Whether it’s projectors, traffic, or wind, this filter ensures clearer voice playback.

Recording Formats: Choose between Linear PCM (larger files capturing more detail, ideal for music) and MP3 (compressed files requiring less memory, suitable for long lectures or meetings). The ICD-PX470 can also play back MP3 and PCM files in music player mode.

Auto Voice Recording: When recording conversations, turn on Auto Voice Recording to optimize audio settings for vocal frequencies. Clear Voice technology further enhances signal clarity during playback.

S-Microphone System: The high-sensitivity, low-noise S-microphone captures distant or quiet sounds naturally and clearly. Even faint audio sources, like distant bird chirping, can be recorded effectively.

Long Battery Life: When using the built-in mic at MP3 192/128kbps, the supplied AAA battery lasts for up to 55 hours, making it suitable for extended recording during conferences and events.

In summary, the Sony ICD-PX470 is a versatile voice recorder that combines convenience, clarity, and extended recording capabilities
