What exactly is online mastering?
Online mastering is the final step in music production. At Peak-Studios, we take your finished mix and refine it to perfection: frequencies are balanced, dynamics precisely controlled, and loudness optimally adjusted to suit the intended release medium.
Imagine simply uploading your song to our platform. We listen to it in studio quality, adjust every detail individually, and deliver a master that sounds competitive on Spotify, CD, or vinyl – without you ever having to visit the studio in person. With our online mastering service at Peak-Studios, professional sound enhancement is available to you anywhere in the world.
At the end, you’ll receive a sonically perfected song that’s fully ready for release on streaming platforms, CD, or vinyl. If you’d prefer to be there in person, we warmly invite you to our recording studio in Würzburg to work with us on the finishing touches – right where your master comes to life.
Planning a vinyl pressing? Take advantage of our specialized vinyl mastering, where we adapt dynamics, side length, and frequency spectrum precisely to the medium’s requirements.

Online Mastering FAQ – Your questions, our answers
What happens during online mastering?
You upload your track via our online form. A professional mastering engineer reviews your mix in a studio-grade environment, evaluates frequencies, dynamics, and stereo imaging, and enhances your sound using either analog or digital processing—based on your preference. You’ll receive a radio-ready master for approval and can request revisions. No AI, no presets—just genuine, handcrafted mastering.
What technical requirements does a good mix need for mastering?
Export your mix as WAV or AIFF in 24-bit with a minimum of 44.1 kHz (ideally: keep your project’s native sample rate). Aim for around −6 dB to −3 dB of headroom, avoid limiters, maximizers or normalizers on the master bus, and ensure there is no clipping. Not sure if everything is correct? Our Mix analysis helps.
What is the difference between analog and digital processing?
Analog mastering: external hardware (e.g., tube compressors, analog EQs) that adds warmth, depth and musical character.
Digital mastering: DAW-based processing and plug-ins – precise, transparent, fully recallable and cost-efficient.
At Peak-Studios, you can choose analog, digital or a hybrid workflow.
What is the difference between online and AI mastering?
Online mastering: A human engineer provides a tailored workflow, critical listening, and revisions based on your feedback.
AI mastering: Fast and inexpensive, but limited in customization, musical judgement and adjustment options. At Peak-Studios, we intentionally rely on human expertise.
What does loudness normalization mean according to EBU R 128?
EBU R 128 defines loudness measurement in LUFS and recommends −23 LUFS for programme loudness, along with monitoring of true peaks (typically ≤ −1 dBTP). This creates consistent playback volume across different platforms. We optimise your master for Spotify, Apple Music, YouTube and more.
What formats do I receive after mastering?
Standard delivery: WAV in 24-bit/48 kHz. On request, we also provide 16-bit/44.1 kHz (CD standard), DDP image, vinyl-ready files or additional preview formats. For physical pressings, we recommend our Vinyl Mastering.
How quickly will I receive my master?
The processing time is typically 3–7 working days after receipt of payment—depending on workload and the desired revision depth.
If you need a faster turnaround, we offer prioritised express processing. Please contact us with your preferred delivery date.
What is stem mastering and when is it worthwhile?
We process grouped tracks (stems) such as drums, vocals or synths individually. This enables precise corrections without unwanted side effects, resulting in more control, depth and overall quality. More information: Stem mastering at Peak-Studios.
