Words? Music? Both? Neither? What Do You Listen For?

I recently saw something on Facebook that caused me to do some serious thinking – not on the subject of music, but that, as I hope you'll agree, is still perfectly applicable to our music listening. It's just one simple sentence: "I never said she stole my money" – but, as the person who posted it pointed out, it can have seven entirely different meanings, depending on which one of the seven words making it up you choose to put the emphasis on: For example, "I never said she stole my money" means something different from "I never said she stole my money", which means something different from "I never said she stole my money", which means something different from "I never said she stole my money", and so on, through the entire sentence, with each new emphasis creating a whole new meaning.

Review: Borresen X2 Loudspeakers

The first track on this album is "The Robots." There are dueling bass lines early in the song, an excellent test of the speakers' low-frequency response and resolving power in this range. Every track on the album has plenty of deep bass, sizzling high-frequency sounds, rather complex arrangements, and a host of other sonic traits. And it is also an excellent album to listen to when I'm not reviewing speakers. I think it's an outstanding album, from start to finish. My first sonic impressions of the Børresen X2s were very, very good. I was impressed with the vast soundstage that surrounded the speakers, and their very good center-fill. On most material, including the Kraftwerk album, the X2's center-fill was superb, it created sharply outlined images in their surprisingly vast soundstage, reminding me of speakers that cost much, much more.

EnjoyTheMusic.com's June High-Performance Audio Review Magazine

We have finalized our in-depth AXPONA show coverage and are still quite busy adding to our very extensive HIGH END 2024 report. Roger Skoff's editorial 'Words? Music? Both? Neither? What Do You Listen For?' asks you which is more important when listening to a song. Even with classical music, where every note to be played by every individual instrument is written down and unchanging, isn't every different performance by every orchestra or every conductor still different! With so much effort going towards show coverage, we still found time to review the impressive Acora Acoustics QRC 2 floorstanding loudspeaker. We also have the North America premiere review of Simaudio's MOON 641 Integrated Amplifier and 681 Network Player / DAC. All this and much more inside EnjoyTheMusic.com's June 2024 Review Magazine.

Auxiliary sends and returns in a mixer serve several important functions in audio production. These features allow for the creation of separate mix busses for specific instruments or vocal tracks, enabling the engineer to apply different effects and processing to each individual channel. By sending a portion of the signal from a channel to an auxiliary send, the engineer can then route that signal to an external effects unit or plugin, such as reverb, delay, or chorus. The processed signal is then returned to the mixer via an auxiliary return, where it can be blended back in with the original signal. This allows for greater flexibility in shaping the overall sound of a mix, as well as creating depth and dimension in the final audio product. Additionally, auxiliary sends and returns can be used for creating headphone mixes for performers in a live setting, allowing each musician to hear a customized mix of their own instrument and others in the band.

An equalizer enhances audio output in a sound system by allowing the user to adjust specific frequency bands to optimize the sound quality. By manipulating the amplitude of different frequencies, such as bass, midrange, and treble, the user can fine-tune the audio to their preferences. This customization can help to correct any imbalances in the sound, improve clarity, and enhance the overall listening experience. Additionally, an equalizer can be used to compensate for the acoustic characteristics of a room or the limitations of the audio equipment, ensuring that the audio output is as accurate and pleasing as possible. Overall, an equalizer plays a crucial role in shaping the sound of a sound system and maximizing its potential.

When looking for a live sound digital mixer, key features to consider include the number of input channels, the presence of built-in effects and processing capabilities, the ability to save and recall presets, the availability of remote control options, the inclusion of high-quality preamps, the presence of a user-friendly interface, the compatibility with various digital audio protocols, the presence of motorized faders for easy mixing, the availability of expandability options for additional inputs or outputs, and the overall durability and reliability of the mixer. These features can greatly enhance the functionality and performance of a live sound digital mixer in a professional audio setting.

Digital signal processors (DSP) enhance sound reinforcement by providing advanced audio processing capabilities such as equalization, compression, delay, and filtering. These processors can optimize sound quality by adjusting frequency response, dynamics, and spatial characteristics to suit different acoustic environments. DSPs also offer features like feedback suppression, room tuning, and speaker management, allowing for precise control over sound reproduction. By utilizing algorithms and digital processing techniques, DSPs can eliminate noise, enhance clarity, and ensure consistent audio performance. Overall, digital signal processors play a crucial role in improving sound reinforcement systems by enhancing audio quality, flexibility, and overall user experience.
