1. ‘engineer’ refers to the audio engineer / producer who is providing the mixing / mastering / production / engineering service.
2. ‘clipping’ refers to the audio level exceeding 0 dB measured in sample peak.
3. ‘DDPi format’ means ‘Disk Description Protocol Image’ and is the most reliable medium for delivering Masters to the factory for pressing. In basic terms, the DDPi consists of a group of files that contain all the audio and relevant meta-data which make up your CD.
4. ‘native sample rate’ refers to the sample rate that the initial files were delivered at by the client.
5. ‘mixed stems’ refers to the mixed groups of instruments which could be used to assemble the mix from, without the necessity of recovering all individual files from the mix session.
6. ‘midi instruments’ refers to virtual instruments (also known as software instrument), used for sound creation on a computer. This can be by imitation of a real instrument, a software sampler or a synthesizer that produces various sounds by using synthesis.
7. ‘other’ in §15 refers to any other services offered by the engineer, such as, studio assistance, production assistance, engineering assistance, co-production, co-writing, performance (either vocal or instrumental).

§1 The files that the client provide must be ready for appropriate services. 

§2 If the clients’ Digital Audio Workstation has a NORMALISE option for exporting audio files, client has to turn that option OFF. In addition, client must make sure that their tracks are not clipping before they export them.

§3 All files must be clearly labelled and numbered. Client can name their files in their preferred way but must be consistent and make sure the files are well organised.

§4 Audio files can be mono or stereo. All audio files must be of the same format (either AIFF or WAV – mp3 formats won’t be accepted) and the same Sample Rate.

§5 The client must consolidate the session into individual files from the start point of your song, including at least 1 bar of silence before the actual beginning of the song.

§6 The client must make sure that all of their files are correct before uploading. For mixing service – if the session contains midi instruments, client must export them as audio – midi files will not be accepted (unless the client will make a request to do additional production on the project).

§7 The multitrack / stems / mixes should be uploaded via WeTransfer (WeTransfer links expire after 7 days, which gives the client better protection over their files, making sure that they will not stay on the internet for unspecified amount of time). Should the size of the folder exceed the free transfer of 2GB, the client must inform EOTPMUSIC LTD in written form, so that a different method of file delivery could be discussed.)

§8 If necessary, mixing and / or mastering revision notes must be sent in written form (either as PDF or via e-mail) and should be sent within maximum of 48 hours after receiving the mix and / or master. Should the client take longer to respond with the revision notes, the turnaround time to finalise said revision may extend.

For mastering – revisions are minor adjustments to the processing. This does not include new mixes or new stems – only replacement that fixes potential issues will be accepted. New mixes, stems, arrangements, etc will be charged as a separate master.

For mixing – minor adjustments to the levels and effects used in the mix. New multitrack / additional multitrack sent for the revision process might be additionally charged.

§9 The client understands and accepts that post-production services, such as editing or quantisation are only applicable if the song was recorded to a click track at the correct tempo of the song. Also, any editing, quantisation or tuning can only be done to certain extent. Excessive use may cause audible artifacts. Post-production service does not include fixing of the performances, but overall enhancements that suits the song. In addition, large amounts of editing might lead to longer turnaround times.

§10.1 For mixing and mastering services, the client will be able to hear the final mix and / or master and all revisions on a private link with an audio player accessing the lossless, full resolution WAV File. Mixing and mastering services include a set of 2 revisions free of charge . Any additional revisions will be charged additional £20 per hour (for every started hour). The client will receive an invoice before the engineer starts any work – full payment must be made upfront. Payment is accepted only via Direct Bank Transfer. The client will receive all applicable files (details in §11) after the final mix and / or master is accepted.

§10.2 For music production service, the client will be able to hear the progress and all revisions on a private link with an audio player accessing the lossless, full resolution  WAV File. The client will receive an invoice before the engineer starts any work – The first payment consisting of the first 50% of the fee must be made upfront. The second payment, consisting the other 50% of the fee must be paid after the client has accepted the final production . Payment is accepted only via Direct Bank Transfer. The client will receive all applicable files (details in  §11) after the second payment has been made.

Any additional costs (where applicable), such as studio hire, transport or travel costs, must be covered by the client.

§11.1 If the client only applies for mixing service, they will receive the following mix files:
WAV file of a Full mix
– WAV file of an Instrumental mix
– WAV file of a Backing track mix

if requested – WAV file of a Radio mix (shortened version and / or clean version without explicit lyrics – this version may be charged additional £20 per hour of work if additional editing would be necessary)

§11.2 If the client applies for mixing and mastering, or just mastering service, they will receive the following master files:
Streaming (.WAV 24 bit – 48 kHz or 96 kHz)
CD (.WAV 16 bit – 44.1 kHz)
Video Distribution (24 bit – 48 kHz)
DDPi format*

*DDP image for physical CD distribution will only be delivered if the following metadata is provided by the client:
– official title of the song / songs
– official title of the Single / EP / LP / Album
– legal names of all songwriters (specified for each song)
– ISRC codes for each song

– UPC / EAN (only if applicable)

In addition, if provided with this type of mix files, they will receive master files (both as .WAV 24 bit – 48 kHz or 96 kHz ) for:
Backing Track

§11.3 If the client applied for music production service, they will receive the following files:
– A folder with 24bit multitrack ready for mixing
– WAV file of a Rough Mix
if requested to do the final mix and / or mix and master, the client will receive the files described in  §11.1 and §11.2.

§11.4 If the client applied for podcast post-production service, they will receive the following files:
– WAV file of the podcast in the resolution of 48 kHz 32 bit
– WAV file of the podcast in the resolution of choice (if specified)

§12 For mixing service, the client WILL NOT receive mixed stems to assemble the mix from. Due to the use of multiple shared effects, shared parallel compression and complex mix bus processing it is impossible to assemble the same mix from different groups of instruments exported separately.

If the client would like to receive a customised set of stems for LIVE performances, they must make a request for these files before any work is done, so that the engineer can adjust the workflow to be able to deliver the most appropriate version of these stems. As the ‘live stems’ are not a part of the initial file delivery package, the stem package will be charged additional £30 (per song) on top of the mixing fee.

§13 The production, mix and the mastering sessions as well as final mixes and masters are backed up on external hard drives after the final files have been delivered (live stem packages are not backed up due to large file sizes for each song). However, sessions might get deleted (if the computer or external hard drives require a format without the possibility of recovering any files) or the session files might get corrupted, therefore, it is the clients’ responsibility to back up their mix / master files, live stem sets, as well as the multitrack files. Once these files have been delivered and paid for, EOTPMUSIC LTD does not take any responsibility: if the client loses them; if the hard drive with backup sessions breaks; if the session file gets corrupted and will not be openable anymore.
None of the clients’ session files, audio files, mixes or masters will be shared with anyone except the client (or any associated person that has been approved by the client to receive those files).

§14 Consultations of any nature will be charged after the 1st session and must be paid before the next one. Should the consultation consist of only one session, it must be paid upfront. The cost of consultation will be specified individually per client. 

§15 The client is obligated to include the appropriate credit in relation to any CD or other record that the engineer has either recorded, edited, produced, mixed or mastered, using the following scheme:

Engineering / Editing / Production / Mixing / Mastering / Other: (choose the applicable)
Krzysztof Kessler


Such credit shall be included in a suitable place in the inner sleeve liner notes of the CD or record and shall be in the same size, typeface and font as any other similar information included in such liner notes.

The client is also obligated to include the same credit (as displayed above) in the description of any YouTube video, Soundcloud player, Bandcamp track (and any other place where applicable) that includes the song that the engineer has either recorded, edited, produced, mixed or mastered.

§16 Should the engineers’ recording and / or producing role extend to programming and performing on the clients’ song (any kind of instrument, virtual instrument or backing vocal), he shall retain all the standard PPL and performance royalty agreements where applicable.

§17 By applying for the services offered by EOTPMUSIC LTD the client gives them the right to use the clients’ songs which they worked on, as an example and portfolio of work to other clients. This includes uploading it to the website (once the song, EP or Album has been released) https://eotpmusic.com/ under the “Credits” panel as a YouTube player or into the built-in audio player. This audio player will not include a download option. A post with the clients’ song on https://eotpmusic.com/ will include all appropriate credits, as well as links to the clients’ social media.
