Stereo Recording Techniques
Mid-side encoding is a stereo recording technique that captures the individual signals of center-panned sounds and information that lies on the left-to-right axis. It combines these signals to create a stereo soundstage that sounds great even when played through a mono sound system.
If you’re interested in recording music or working in the audio industry, mastering the art of stereo recording techniques is essential. It’s all about capturing sound in a way that accurately represents its natural placement in relation to the listener. Mid-Side Encoding is one such technique that’s gaining popularity among music producers and artists worldwide.
Coincident Pair
The coincident pair stereo recording technique uses two directional microphones placed close to each other, with their capsules arranged so that they’re pointing at a 90-degree angle away from one another. This microphone placement is also known as XY stereo recording. The closer the microphones are placed together, the more coherent the sound will be. This technique works extremely well for capturing mono sources like guitars, pianos, and vocals.
Spaced Pair
The spaced pair technique makes use of two omnidirectional microphones placed a distance apart from each other. The distance between the microphones can be adjusted to alter the stereo image. If the microphones are spaced too far apart, the recordings will have a weak center image and more room ambiance. If they’re too close, the recordings will sound phasey and unnatural. This technique works exceptionally well for recording drum overheads, string sections, and orchestras. When using a stereo recording technique, it’s essential to consider the microphone choice and placement. Mid-Side Encoding takes the stereo recording technique to another level by giving more control over the stereo field’s width and making it sound bigger and more spacious. It’s a perfect choice for a wide range of sound sources, especially drums, and acoustic guitar recordings.
What Is Mid Side Encoding?
Mid Side Encoding (M/S) is an audio processing technique that allows you to separate a stereo audio signal into two component signals – the Mid signal and the Side signal. The Mid signal represents the audio information that is common to both the left and right channels, while the Side signal contains the audio information that is different between the two channels. The outputs of the Mid and Side signals can be independently adjusted, processed, and recombined to recreate the original stereo signal. M/S encoding is commonly used in audio mastering and mixing, as well as in certain audio codecs that apply lossless compression techniques.
Definition
Mid Side Encoding (M/S) is a technique for separating a stereo audio signal into two component signals – the Mid signal and the Side signal. The Mid signal represents the audio information that is common to both the left and right channels, while the Side signal contains the audio information that is different between the two channels. The Mid and Side signals can be independently processed, adjusted, and recombined to recreate the original stereo signal.
How It Works
M/S encoding works by subtracting the Right channel from the Left channel to obtain the Side signal, and adding the Left and Right channels together to obtain the Mid signal. Mathematically, M = (L + R)/2, and S = (L – R)/2. The Mid and Side signals can then be modified, either in the time or frequency domains, using digital signal processing techniques, such as EQ, compression, and stereo imaging. Once the processing is complete, the Mid and Side signals are combined to create the stereo signal using the formula L = M + S and R = M – S.
- Greater control over the stereo image and width of a mix
- The ability to rebalance the levels of the center and stereo components of a mix
- The ability to apply EQ and other processing to the center and/or stereo components independently
- Improved compatibility with certain lossless audio codecs
Conclusion
Mid Side Encoding is a powerful technique that audio engineers use to gain greater control over stereo mixes and improve compatibility with certain audio codecs. By dividing a stereo signal into its Mid and Side components, you get more flexibility in shaping the stereo image and can make more precise adjustments to the overall mix. With M/S encoding, you can create richer soundscapes that sound great on any playback system.
Benefits Of Mid Side Encoding
Mid side encoding is a technique used in audio recording to separate the mono and stereo components of a signal. It provides benefits such as greater control over stereo width and a better overall sound balance. With this technique, users can obtain a more detailed and accurate sound image in their recordings.
If you are not familiar with Mid Side Encoding, it is a stereo audio processing technique that encodes the center information separately from the sides. It offers several benefits in music production and audio engineering, and we will look at some of these benefits in this section.
Improved Mono Compatibility
One of the primary benefits of Mid Side Encoding is improved mono compatibility. When an audio mix is summed to mono, the left and right channels are combined, resulting in potential phase cancellation and audio loss. However, with Mid Side Encoding, the center channel remains intact, providing a stable mono mix. This technique ensures that the audio you mix in stereo remains fat and powerful when heard in mono.
Simplified Stereo Processing
Another benefit of Mid Side Encoding is simplified stereo processing. With this technique, the sides and center can be processed separately and independently. This provides more creative options for audio processing, including stereo widening and image enhancement. Additionally, it allows for easy balancing of the center with the sides, resulting in improved stereo imaging. If you are an audio engineer or music producer, Mid Side Encoding can be a valuable tool in your audio processing arsenal. It provides improved mono compatibility and simplified stereo processing, making it easier to create powerful and balanced audio mixes.

Ms Processing In Live Sound
Mid-side encoding (MS) is a technique used in live sound to adjust the stereo width of audio signals. It involves encoding the stereo signal into a mid signal, which contains the audio information that appears in both left and right channels, and a side signal that contains the audio information that only appears in one of the channels.
This approach can be helpful in reducing the phase cancellation issues that can occur when processing stereo signals, making it a popular technique in recording and mixing.
Using Ms Techniques In Live Sound
MS (mid-side) processing in live sound refers to a technique that involves encoding the stereo audio signal into mid and side components. This technique allows sound engineers to work with the individual components separately and produce a better-sounding mix. When using MS techniques in live sound, the mid component can be used to adjust the level and clarity of the center-panned sounds, such as vocals, bass, and kick drum, while the side component can be used to adjust the width and spatial characteristics of the stereo sounds, such as guitars, keyboards, and cymbals.
Common Problems And Solutions
While MS processing in live sound offers many benefits, it can also introduce specific issues that sound engineers may encounter. One common problem is the phase cancellation between the mid and side signals. This can result in a weaker and narrower sound. The solution to this problem is to ensure that the phase relationship between the mid and side signals is maintained. This can be achieved by using a tool that processes with high-quality digital encoding and decoding algorithms, such as a mid-side processor. With this tool, the phase relationship can be adjusted and corrected, resulting in a more natural and balanced sound. Another issue that can arise when using MS techniques is unwanted noise, particularly in the side channel. This can be caused by interference from radio signals or ambient noise in the recording environment. The solution to this is to filter out the noise frequencies using a high-pass filter. It is important to carefully adjust the filter to avoid filtering out essential frequencies in the recording. In conclusion, MS processing in live sound is a powerful technique that allows sound engineers to achieve greater control and flexibility over their mix. With careful attention to phase relationships and noise filtering, MS processing can help produce a high-quality, natural-sounding mix that will delight audiences.
