RoomPerfect™ – improving the loudspeaker performance in your room
One of the world’s most sophisticated solution for adapting loudspeakers to the room acoustics. RoomPerfect™ addresses room acoustical issues without compromising the sound of your loudspeakers.
What is RoomPerfect™?
RoomPerfect™ calibrates the loudspeakers to the room they are in and addresses room acoustical issues, for example exaggerated bass, lack of bass, uneven bass, or diffuse imaging and soundstaging. RoomPerfect™ removes these issues in the audio signal and allows your speakers to perform at their best.
Why is RoomPerfect™ better?
Calibrated RP microphone and extended RP calibration signal ensure a reliable measurement and greater resistance to interference.
3DMAP acoustically maps the room in 3D and achieves a better room knowledge.
AdapTC sets an adaptive target curve and retains the loudspeaker’s inherent sound performance and musicality.
RoomPerfect™ is made for listening. Instead of the common sound linearization, the psychoacoustic perception of sound in a room is acknowledged in the calibration algorithm.
Ease of use without requiring an external computer, plug-in, program, or master degree in speaker calibration.
What does RoomPerfect™ do?
With the RoomPerfect™ microphone and a specifically created measurement signal, RoomPerfect™ measures the speaker’s power response in the room. It then separates room acoustical issues from the actual speaker sound, and applies corrections to the audio signal in the digital domain. RoomPerfect™ also improves the performance of speakers in conjunction with subwoofers.
Who is behind RoomPerfect™?
RoomPerfect™ was developed by a team of leading acoustic engineers and DSP experts from Denmark, who have worked with speakers and room calibrations for over 25 years. The team was led by Peter Lyngdorf, who pioneered digital audio amplifiers and speaker calibration, and founded Lyngdorf Audio in 2005.
How can I get RoomPerfect™?
RoomPerfect™ is implemented in the DSP (Digital Signal Processing) of Lyngdorf TDAI stereo amplifiers and Lyngdorf MP multichannel processors. It is also available in Steinway Lyngdorf systems, discontinued Lyngdorf products, and select McIntosh electronics.
Is RoomPerfect™ easy to use?
RoomPerfect™ is very easy to use, either with the Lyngdorf app on a smartphone or tablet, or operating the device with the remote control. No computer, screen, software, nor calibration knowledge is required. RoomPerfect™ works with every loudspeaker and in every room, from home theaters to studios and living rooms.
The original RoomPerfect™ microphone
As with every measurement device, capturing reliable data in the first place is extremely important. If the acoustics are not measured correctly, the whole calibration will be wrong, and the resulting sound performance deteriorates. The RoomPerfect microphone is designed and calibrated specifically for Lyngdorf Audio and has the ideal properties: A high-quality, omni-directional microphone capsule housed in a sturdy aluminium tube, with a shape that tapers towards the front to disturb the soundwaves the least. It also provides a very good signal-to-noise ratio with exceptionally low distortion. It is simply the best starting point to ensure the most reliable calibration.
Developed by the pioneers of speaker calibration
The RoomPerfect recipe: Take over 25 years of experience in room acoustics. Based on that, completely rethink speaker calibration. This is what a team of leading acoustic engineers and DSP experts from Denmark did in 2005, led by digital audio innovator Peter Lyngdorf. Some of their experience even dated back to 1993, when they developed the first RCS processor, a product way ahead of its time. Recognizing why even today many common calibration systems are not always preferred by listeners, they developed a new, unique, and better approach.
The people behind RoomPerfect™
Peter Lyngdorf
Digital audio innovator Peter Lyngdorf pioneered speaker calibration, starting with the market’s first system RCS already in the 1990s and driving forward RoomPerfect after founding Lyngdorf Audio in 2005.
Jan Abildgaard Pedersen
Jan’s combination of room acoustical expertise and DSP engineering is rare and was the perfect foundation for developing RoomPerfect. He is an active and awarded member of the AES, Audio Engineering Society.
Kasper Thomsen
Kasper is an experienced DSP software engineer, always striving for the best audio and speaker performance. He is a key member of the development team who created the patented RoomPerfect calibration.
Thomas Birkelund
The CEO and CTO of Lyngdorf Audio always has the end user in mind and was the driving force to make RoomPerfect both technically advanced, but still easy to use for everyone.
“I cannot overemphasize how important and how amazing RoomPerfect calibration is. The definition of the instruments, the placement of the instruments was so phenomenal, I almost couldn’t believe it.”
“RoomPerfect in the MP-60 elevates an already impressive product to the top of my list of best processors.”
“The bass peaks had gone, and I got a much, much smoother bass response in the room. But, crucially, RoomPerfect doesn’t fundamentally alter the character of the speaker.”
” For those of us with less-than-ideal rooms, which is most of us, I can’t think of a single more useful feature than a state-of-the-art room-correction system like RoomPerfect.”
“With RoomPerfect the impression of realism was further enhanced. Regular stereo seems blurry by comparison.”
“The audible results with RoomPerfect are definitely convincing, they are more homogeneous and much less artificial than other room corrections.”
“Switching RoomPerfect on/off had a major impact! The soundstage really opened up, with added height and depth. I was drawn more into the music; the experience became more enveloping.”
The 10 secrets of RoomPerfect™
RoomPerfect™ is one of the world’s most sophisticated and advanced solution for calibrating speaker to the room. But what is so different?
1
Most room calibrations end after measuring at the listening spot. That’s where RoomPerfect only starts.
RoomPerfect™ starts as any other calibration: With the microphone at the main listening position. Typically, the sound will be linearized based on this single spot. However, when listening to music, soundwaves build up over time, across the room. RoomPerfect’s 3DMAP takes more measurements across the room and using an extended signal. This is the key to a better calibration.
2
Most room calibrations don’t measure the room. They don’t measure the speaker either.
The common one-spot approach is very limited: One single frequency response gives no indication what causes the acoustical issues, and whether it is the speaker’s original response, or the room response, or both. 3DMAP maps the room and measures the speaker’s power response. With every measurement it becomes more clear what your room is like, and what your speakers are like.
3
What is the loudspeaker’s worst enemy? The room. What is the loudspeaker’s best friend? The room.
Most calibrations see the room as an acoustical problem. Every deviation from an imagined linear target curve will be linearized. In reality, speakers are made for rooms. The key to a more satisfying sound performance is not to correct and linearize everything. RoomPerfect preserves what sounds good with your speakers in your room, isolates the room acoustical issues, and only corrects these.
4
The earth isn’t flat, and linear doesn’t sound good either.
The linear target curve is the basis for most electronic calibrations and room treatments. However, it is not what music listeners perceive as good sound in a room. A linear frequency response is not what you should aim for, unless you live in an anechoic chamber. It should also not be forced on every loudspeaker. RoomPerfect™ with AdaptTC takes a more intelligent approach: it preserves the speaker’s best sound performance in the room.
5
Introducing the most critical measuring device: Your ears.
RoomPerfect™ has been developed by acoustic engineers and DSP experts with a scientific approach, so it comes as a surprise that it doesn’t force a linear frequency response on every speaker and every room. RoomPerfect™ understands room acoustics more thorough and also incorporates psychoacoustics. With loudspeakers, there can only be one goal: A better sound experience with music and movies, as perceived by the listeners.
6
Beware! If you are not dead-silent while measuring… it’s no problem at all.
Most calibrations are extremely sensitive to noise and disturbance during the measurement. Even when every person in the room remains quiet, any sound from inside or outside the room can affect the measurement. If detected, it requires to re-run the measurement. If not, it secretly leaks into the correction signal. RoomPerfect™ uses a proprietary extended multi-tone measuring signal. This ensures a reliable measurement and astonishing resilience to interference.
7
Bass traps: It’s a trap.
Bass traps are often considered to counter exaggerated bass. However, they do what they are designed for: Absorbing all the bass. Broadband. Regardless of the actual problem frequency. It is much more intelligent and precise to solve the problem in the signal domain. RoomPerfect™ is exceptionally good at detecting and addressing acoustical problems without leading to a lean or dynamically compromised sound. Instead, the bass remains powerful and deep.
8
Never correct what doesn’t need to be corrected.
The infamous linear target curve means that everything above and below an imagined flat line will be corrected. The result looks very good in a graph, but sound and visuals are not the same. RoomPerfect™ with AdaptTC never over-corrects. It doesn’t linearize everything nor force a linear frequency response on every speaker. RoomPerfect™ understands the room as well as your speakers, and preserves the best of both.
9
How many dB does it take to fill a null?
Some corrections detect a dip in the frequency response, for example a room node, and try to fill it up. Following the usual one-spot linearization, the algorithm knows no better. However, a so-called null cannot be filled – it is an acoustic black hole. This can easily overpower your speakers and amplifier, limit their dynamic headroom, and increase distortion. RoomPerfect™ understands room acoustics and speakers much better, and never overcorrects.
