LS-P4

Meet the compact LS-P4 with FLAC compatibility and Bluetooth connectivity. Experience high-resolution recording anywhere, anytime.

The pocket-sized LS-P series packs the advanced technology of Olympus’ flagship LS series linear PCM recorders into a portable size. The new LS-P4 is the first linear PCM recorder from Olympus compatible with the FLAC lossless format which provides high-resolution recording – beyond that of CD-quality audio, in compressed file sizes while maintaining the same sound quality as linear PCM. Using capable speakers or headphones, you can wirelessly playback and share your recorded audio with friends, cable-free thanks to the LS-P4’s built-in Bluetooth connectivity. The compact and stylish design in a robust metal body offers convenience and portability, so you never miss a sound.

Functions added or improved through firmware version 1.10

A)New functions have been added to the LS-P4, which enables high quality sound for video shooting and easy editing when used together with a digital camera

  • These functions can be used with digital cameras that have a microphone input jack.

A)-1. Slate Tone Function
This function generates and records a signal as a reference position on both the video and sound file, in the digital camera and the LS-P4. The Slate Tone makes it is easier to synchronize video and sound when using video editing software.
