Radio. Every second counts. Program segments need to start and end exactly on time, with seamless transitions. Editing time is precious in the production room and in the field. If your piece is just a bit long or a bit short, will the pressures of getting it on air force compromising edits or inappropriate filler?
Enter the 25-Seven Program Length Manager (PLM) to shrink or stretch your programs and program segments by 5% (three minutes per hour) or even 10%-without pitch change, artifacts or glitches. Time-manipulated audio is clean enough to use on stereo music programs and live events. PLM is operator friendly and requires little training whether controlled from the front-panel or via web browser.
PLM is the next best thing to being able to stop the clock or add more minutes to the hour. Now, you're free to focus on creative radio and let PLM assure continuity. That syndicated or brokered program and your local content don't add up to the allotted slot? PLM can stretch the program to fit without the need for filler material or extra production steps. Need to insert some additional material without program interruption? Easily accomplished with PLM and not perceived by your listeners.
25-Seven's all-new time expansion algorithms inaudibly stretch under-length programs to fit their time slots. Intuitive operator controls make it easy. Just enter the actual program length and target playout length. Then, PLM recommends a stretch rate and shows you the time at which the stretch function will be completed. PLM looks at the entire program, eliminating the need to adjust individual program elements, such as spots or songs. You can then adjust the stretch rate and the point in time that PLM returns to real time to suit your preferences.
PLM offers two ways to shrink a program: On-the-fly BUFFER+PLAY provides a quick way of pausing your main program while inserting other content. Trigger PLM from the front panel or remotely and the main program is recorded until you command the unit to start playing out. The PLM smoothly plays the buffered audio until it rejoins real time. During the playout, you can manually adjust the compression rate and rejoin time. Preprogrammed SHRINK TO TARGET works like the program stretch function, allowing advance computation of program length and compression rate.
PLM uses advanced time manipulation algorithms that don't affect pitch and don't add harmonic distortion or frequency limitations. Our proprietary algorithms intelligently process speech-stereo music stays clean and steady. No choppiness, no stutters, no fuzziness.
The front-panel LCD “dashboard” has controls for time readout, audio level display, and allows quick parameter changes. Flexible remote control options include user assignable GPIO (buttons, relay closures, or TTL), secure Web interface, RS-232 or serial control over an IP port. Navigating though “set and forget” parameters via LAN or WAN is a breeze with the internal password-protected Web server. Superior balanced analog I/O and AES digital are standard. Even during time manipulation, PLM boasts 84 dB S/N with 10 dB headroom, frequency response of 20 Hz-20 kHz (±0.5dB) and 0.01% THD+N.
