+abstract: |
+  The Procedural Engine Sounds Dataset is a comprehensive collection of 
+  synthetically generated and annotated engine audio samples. This dataset 
+  contains procedurally generated engine sounds with detailed annotations 
+  encoded as 4-channel audio, designed for research in audio processing, 
+  vehicle acoustics, and synthetic sound generation. The dataset includes 
+  5,935 high resolution audio files (48 kHz, 16 bit) totalling ~19 hours 
+  and 24.47 GB of content across 8 distinct sets, with RPM and torque 
+  information embedded as continuous audio signals alongside stereo engine sounds.

+
+  l. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part, for NonCommercial purposes only; and
+
+            b. produce, reproduce, and Share Adapted Material for
+               NonCommercial purposes only.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties, including when
+          the Licensed Material is used other than for NonCommercial
+          purposes.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database for NonCommercial purposes
+     only;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+Each audio file contains **4-channel audio** at 48 kHz sample rate:
+- **Channel 1-2**: Stereo engine sound audio
+- **Channel 3**: Engine speed (RPM × 0.0001) as continuous audio signal
+- **Channel 4**: Engine torque (Nm × 0.001) as continuous audio signal
+
+### Metadata Structure
+
+#### Summary Files (.json)
+Per-set statistics including:
+- `num_files`: Number of audio files in set
+- `total_duration_*`: Duration in seconds/minutes/hours
+- `total_size_gb`: Storage size in GB
+- `rpm_distribution`: Statistical distribution (min, max, mean, std, percentiles)
+- `torque_distribution`: Statistical distribution (min, max, mean, std, percentiles)
+
+#### Statistics Files (.csv)
+Per-file metrics with columns:
+- `filename`: Audio file name
+- `samplerate`: Sample rate (48 kHz)
+- `duration_sec`: File duration in seconds
+- `size_MB`: File size in megabytes
+- `rpm_min/max/mean/std`: RPM statistics for the file
+- `torque_min/max/mean/std`: Torque statistics for the file
+
+### Data Access
+
+Each audio file is a standard WAV file containing a 4-channel audio array at 48 kHz sample rate. When loaded, you receive the raw multichannel audio data from which RPM and torque information can be extracted from channels 3 and 4 respectively.
+
+### Audio Signal Encoding
+
+- **RPM Signal**: Channel 3 contains engine speed values in RPM scaled by 0.0001 (multiply by 10,000 to get actual RPM)
+- **Torque Signal**: Channel 4 contains torque values in Newton meters scaled by 0.001 (multiply by 1,000 to get actual Nm)
+- **Engine Audio**: Channels 1-2 contain the stereo procedural engine sound
+
+## Technical Requirements
+
+To work with this dataset, you will need:
+- Audio processing software capable of reading multi-channel WAV files
+- Programming languages: Python (recommended with librosa, soundfile, or scipy), MATLAB, R, or similar
+- For metadata: JSON and CSV reading capabilities
+
+## Dataset Creation
+
+### Source Data
+
+All audio samples are synthetically generated using procedural audio synthesis techniques. 
+No real-world engine recordings were used for audio generation. 
+Dataset results were thoroughly analysed and compared to real world recordings to verify representativeness and similarity regarding engine order magnitudes and harmonic deviations.
+
+### Annotations
+
+Annotations were created during the generation process, with additional manual verification for quality assurance.
+
+## Considerations for Using the Data
+
+### Social Impact of Dataset
+
+This dataset enables research in:
+- Automotive audio simulation
+- Vehicle sound design
+- Audio processing algorithms
+- Synthetic data generation techniques
+
+### Discussion of Biases
+
+As a synthetic dataset, it reflects the biases inherent in the procedural generation algorithms and may not capture all real-world engine sound variations.
+
+### Other Known Limitations
+
+- Limited to procedurally generated sounds
+- May not represent all engine types or acoustic environments
+- Generated with empirically determined synthesis parameters, hence contains fictional engine types and exhaust pipe configurations

+USAGE.txt - Procedural Engine Sounds Dataset
+==========================================
+
+QUICK START GUIDE
+-----------------
+
+This dataset contains 4-channel WAV audio files with engine sounds and embedded RPM/torque data.
+
+FILE STRUCTURE:
+- audio/[A-H]_*_set/: WAV files organized in 8 sets
+- metadata/: JSON summaries and CSV statistics for each set
+
+AUDIO CHANNEL LAYOUT:
+- Channel 1-2: Stereo engine sound audio
+- Channel 3: RPM values (multiply by 10,000 for actual RPM)
+- Channel 4: Torque values (multiply by 1,000 for actual Newton-meters)
+
+BASIC USAGE EXAMPLES:
+
+1. PYTHON (with soundfile):
+   ```python
+   import soundfile as sf
+   import numpy as np
+   
+   # Load a 4-channel audio file
+   audio, sr = sf.read('audio/A_full_set/engine_001.wav')
+   
+   # Extract channels
+   engine_left = audio[:, 0]      # Left engine audio
+   engine_right = audio[:, 1]     # Right engine audio  
+   rpm_signal = audio[:, 2] * 10000   # RPM values
+   torque_signal = audio[:, 3] * 1000 # Torque in Nm
+   ```
+
+2. PYTHON (with librosa):
+   ```python
+   import librosa
+   
+   # Load specific channels
+   engine_audio, sr = librosa.load('audio/A_full_set/engine_001.wav', 
+                                   sr=48000, mono=False)
+   # Result shape: (4, samples) - channels x samples
+   ```
+
+3. MATLAB:
+   ```matlab
+   [audio, fs] = audioread('audio/A_full_set/engine_001.wav');
+   
+   engine_left = audio(:,1);
+   engine_right = audio(:,2);
+   rpm = audio(:,3) * 10000;
+   torque = audio(:,4) * 1000;
+   ```
+
