MASTERING ACADEMY GmbH, Großmannstraße 213, 20539 Hamburg

and you as our customer. The terms and conditions apply regardless of whether you are a consumer, entrepreneur or merchant.

(2) All agreements made between you and us in connection with the contract of sale or seminar registration arise in particular from these conditions of sale, our written order confirmation and our declaration of acceptance (confirmation of registration).

(3) Decisive is the version of the GTC valid at the time the contract is concluded.

(4) We do not accept deviating conditions of the customer. This also applies if we do not expressly object to the inclusion.

  • 2. Contractual Object

(1) We offer our customers the provision of further education, coaching, seminars and consulting services – multimedia, video-based, telephone and stationary. Depending on your booking, the coaching and consulting services are standardized or individualized. The respective service description results directly from our offers and product descriptions.

(2) In addition to the provision of the services booked by the customer, we owe the customer no particular success. The booking of our services is usually done using remote communication means, but is not limited to this.

(3) We provide services for our customers in the field of audio engineering / sound engineering education. The MASTERING ACADEMY GmbH has specialized in particular on the imparting of skills in the area of non-linear sound engineering activities (mixing & mastering) as well as of contents, which are usually not sufficiently covered in the context of regular university or private-institutional audio-technical training.

Unless expressly agreed otherwise in writing, we do not owe the provision of a work. In particular, we can only predict the success of certain measures based on experience. The customer is aware that we do not owe this success to our customer because the prerequisites and specific parameters regarding the will to learn, ability to learn, talent, commitment and implementation of the learned content are unpredictable.

(4) With regard to the content of a training, coaching, service, and / or consulting contract we have closed, we are entitled to a right to determine performance according to § 315 BGB (Leistungsbestimmungsrecht).

  • 3. Conclusion of Contract

(1) The presentation and promotion of our services on our websites, brochures or within advertisements (eg on Facebook) does not constitute a binding offer to conclude a contract with us.

(2) The contract between us and the customer can be made by telephone (video chat, telephone, etc.) or in writing. If the contract is concluded by telephone, the customer is not entitled to receive the contract contents in written form from us, unless otherwise agreed. If the conclusion of the contract takes place by telephone, you can correct your information to us at any time by simple message to your partner at MASTERING ACADEMY.

(3) Via telephone contracts come about through consensual declarations of intent between us and the customer. The customer agrees that we record the telephone conversation with him and / or the respective video chat for evidence and documentation purposes.

(4) We will confirm the receipt of your orders and orders via e-mail, our website / video chat immediately by e-mail. In such an e-mail there is still no binding acceptance of the order, unless in addition to the confirmation of receipt the binding acceptance is expressed at the same time. In case of a video chat, our declaration of acceptance may already take place in direct conversation with you.

(5) If the performance of the services you have ordered is not possible, for example for technical reasons or a lack of course capacity, we will refrain from a binding acceptance. In this case, a contract is not concluded. We will inform you about this without delay and, if necessary, immediately refund already received payments.

(6) Should it not be possible to start the course at the earliest possible time due to a lack of course capacities, a delay of up to 8 weeks in the beginning of the course is reasonable. If no substitute course is available within 8 weeks after the originally planned start of the course, the course fee will be refunded immediately.

(7) The contract language and the language of the course is German for German courses and English for English courses.

(8) The offer / contract text will be stored after the conclusion of the contract by us according to specifications of the DS-GVO. Further details can be found in the privacy policy. The contracts recorded by telephone are not automatically transcribed and therefore can not be accessed by the consumer.

  • 5. Delivery & Service Conditions

(1) The duration of the coaching or the seminar / course is shown in the product / course description.

(2) Technical prerequisite for the smooth running of the seminars:

To enable high-quality coaching, we need to be able to engage in mutual screen sharing and play uncompressed audio from your DAW and play audio from us in other situations while communicating with you at the same time. Please comply with the following easy to meet minimum requirements:

Participants / customers should have a stable internet connection (ideally LAN) on the used audio workstation (10MBPS download and 4 MBPS upload or more).
The audio card used should either have a loopback function to route the Masterbus output back to an input where we can tap it, or to physically route the Masterbus output to a second physical input via split cable or by routing the Masterbus out internally to a second output in order to loop the signal back from there.
The sound card used should be adjustable to 1024 samples latency in streaming mode.
The sound card should be accessible via ASIO or Core Audio driver.
Participants need a simple camera and possibly a headset for communication during the coaching sessions. It is crucial to separate the talk back communication from the pure high-res audio connection by using e.g. the build in microphone of the USB camera or USB headset while the audio is streaming through the sound card.
Employees of the Mastering Academy help participants with the setup of the technical equipment of the communication tools. In addition to these technical prerequisites, participants are not required to pay extra services fees for conducting the seminars. The Mastering Academy offers participants free software tools if necessary. For the failure or partial failure of seminars due to non-fulfillment of the technical requirements Mastering Academy is not liable.
