Pith's one-line read The paper introduces a new 88-hour dataset of healing sounds and a 57.4% MFCC baseline for classifying them.
desk verdict The ASW dataset is a plausible first for acoustic wellbeing audio, but the paper's central claim is unverifiable because the data is not actually available, and the 'completely mis-classified' chanting statement conflicts with the paper's own confusion matrix. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The carrying object is the ASW dataset itself: 68 video-derived audio files totaling 88:03 hours, split into 5,283 60-second chunks over three independent partitions. The classification baseline uses 20 MFCCs extracted with a standard audio toolkit and a linear-kernel support vector machine, with complexity optimized on a validation split and final results reported on held-out test chunks. A second feature set, 4,096-dimensional deep representations from a pre-trained VGG19 network, is included for comparison and performs worse, which the paper interprets as evidence that the long 60-second chunks suit conventional features better at this stage.
What would settle it
Take a random sample of chunks and have three independent annotators label each by ear; if agreement falls far below the level implied by the baseline, or if a large share of chunks is reassigned, the labels and the 57.4% result would not stand.
Extended reading notes
Core claim
The central claim is that the ASW dataset, collected from creative-commons YouTube videos and cleaned by brief manual listening, is a viable large-scale resource for acoustic wellbeing research. On that dataset, a linear SVM trained on 20 Mel-frequency cepstral coefficients achieves 57.4% unweighted average recall across all five classes, about 37 percentage points above chance; the same pipeline reaches 75.5% on the two-class gong-versus-singing-bowl task. The chanting class is almost entirely misclassified in the five-class setting, which the authors attribute to its small size and acoustic variability.
Load-bearing premise
The dataset's usefulness depends on the assumption that the YouTube search terms and the authors' brief listening pass correctly labelled every chunk into one of the five classes, with no independent verification.
Editorial extensions
If this is right
- Future work on classifying wellbeing audio can compare against a fixed ASW train/validation/test split instead of building ad hoc collections.
- The 57.4% unweighted average recall becomes the headline benchmark; later feature sets or models need only beat it on the same partition to show progress.
- The dataset is large enough to support conditional audio generation or soundscape augmentation experiments, as the authors propose for future work.
- Because chanting hurts overall performance, a dedicated collection effort for that class would likely improve multi-class results.
Reading between the lines
- A testable extension would be to re-annotate a random sample of the 5,283 chunks with several listeners and measure inter-annotator agreement; high agreement would strengthen the dataset's label validity, while low agreement would call the 57.4% baseline into question.
- The YouTube search strategy likely tracks a 'sound healing' genre as much as acoustic classes; separating instrument acoustics from recording style could be a follow-up experiment.
- Because the paper notes that speech was difficult to remove completely, a future version could quantify how much vocal content remains and test whether classification is driven by voice detection rather than instrument identity.

Referee Report
Summary. The paper introduces the Acoustic Sounds for Wellbeing (ASW) dataset, 88+ hours of YouTube-derived audio in five classes (Gongs, Drumming, Chimes, Singing Bowls, Chanting), together with baseline classification experiments using MFCC and Deep Spectrum features with a linear SVM. The authors report unweighted average recall (UAR) up to 57.4% for the full five-class task, noting that the chanting class is difficult. The central claims are that the dataset is a novel resource for sound-healing research and that the baselines provide a reference for future work.
Significance. If the dataset is made publicly available and the reported numbers are verified, the ASW dataset could be a useful community resource for soundscape analysis, audio generation, and wellbeing-related audio research. The baseline classification results, while modest, provide a reasonable starting point for future methods. The paper's use of a held-out test partition is appropriate. However, the contribution is currently not verifiable because the dataset itself is not accessible, and several internal inconsistencies in the data description prevent the reader from trusting the reported statistics.
major comments (4)
- [Section 2, footnote 1] The dataset is the central deliverable of this paper, but it is not available: footnote 1 says 'link will be added upon acceptance' and the posted version provides no URL or repository. Without public access, the claimed 68 clips, 5,283 segments, 88:03 total duration, and the classification results cannot be independently confirmed or used by the community. A working download link and a detailed description of the release (file formats, directory structure, metadata, licenses) must be provided before the dataset claim can be accepted.
- [Table 1] Table 1 contains an internal inconsistency that undermines the data description. The class rows sum to 34+35+35+34+15 = 153, while the total number of videos is stated as 68 in the '# videos' row; the column sums of the class rows (55, 49, 49) also do not match the partition sizes (24, 22, 22). Either the row/column meanings are mislabeled, or the entries are for a different quantity (e.g., number of segments), but as printed the table is self-contradictory. This needs to be corrected and clarified.
- [Section 4, Figure 2(d)] The text states that 'for the 5-class classification (experiment 4), the chanting (cha) class is completely mis-classified,' but the confusion matrix in Figure 2(d) shows 18 correct predictions for the cha row, corresponding to a per-class recall of 18/68 ≈ 26.5%, which is above the 20% chance level. The claim of 'completely mis-classified' is therefore factually incorrect and should be revised to a more accurate characterization, such as 'poorly classified with recall near chance-level but not zero.'
- [Section 2.2] The label quality is load-bearing for the dataset's validity, yet the manual listening step is described only as 'listened over briefly' to check 'quality and presence of any additional audio.' No inter-annotator agreement, explicit inclusion/exclusion criteria, or thresholds (e.g., what counts as 'excessive speech') are provided. Since the chanting class was created from drumming search results and the paper reports that speech could not be fully removed, the authors should provide a clearer annotation protocol or at least a quantitative estimate of label purity to support the dataset's use as ground truth.
minor comments (6)
- [Abstract] The abstract says '5-classes of acoustic instrumentation (Gongs, Drumming, Singing Bowls, and Chanting)' but lists only four classes; Chimes is missing and should be added.
- [Section 3.3 and Table 2] The 'Dev.' column in Table 2 is not clearly defined; the text says complexity is selected on the validation set, but it is not stated whether Dev. reports validation performance of the selected model before retraining on the concatenated train+validation sets. The large gaps between Dev. and Test values (e.g., 34.8% vs. 80.5% in experiment 2) warrant an explicit explanation.
- [Section 3.2] The Deep Spectrum extraction is insufficiently specified for reproduction: the paper should state the exact version of the toolkit, the input representation details (e.g., spectrogram window size and hop length), and whether the VGG19 network was used with ImageNet weights or with any fine-tuning.
- [Figure 2] The confusion matrices are not annotated with axis labels; the authors should indicate which axis corresponds to true class and which to predicted class.
- [Section 2.1] The crawling date, the total number of videos downloaded, and the number of videos discarded at each post-processing step are not reported. Providing these numbers would help assess the data collection process.
- [Throughout] There are minor language and typographical errors, including 'significant affect' in the introduction (should be 'effect'), 'affective' in the conclusion (should be 'effective'), and 'reptitious' for 'repetitive' in the description of drumming. A careful proofread is recommended.
Circularity Check
No significant circularity: the baseline accuracies are measured on a held-out test partition and are not fitted to match a target.
full rationale
This paper makes no derived prediction that reduces to its own inputs. The central empirical claim is the 57.4% UAR 5-class SVM result on MFCC features (Section 4, Table 2, Figure 2d). That result is obtained by training on a training partition, selecting the complexity parameter C on a validation partition, and reporting performance on an unseen test partition, as described in Section 3.3 ('Upon selection of the best performing complexity we report final test results on the unseen test partition against the concatenated train and validation sets'). The class labels come from YouTube search terms plus manual listening (Sections 2.1-2.2), and the classification performance is measured against those labels on held-out data; there is no fitted parameter that is renamed as a prediction. The dataset's validity and availability are separate concerns: the footnote 'link will be added upon acceptance' means the dataset is not yet verifiable, but unavailability is an audibility/reproducibility issue, not circular reasoning. The authors' citations of their own prior work (e.g., [11], [12], [38]) are used as background or as a feature-extraction toolkit, not as the load-bearing justification for the baseline result. No step in the paper defines a class, feature, or metric in terms of the target outcome, and no claimed result is equivalent to its input by construction. The honest finding is therefore no significant circularity.

The field of sound healing includes ancient practices coming from a broad range of cultures. Across such practices there is a variety of acoustic instrumentation utilised. Practitioners suggest that sound has the ability to target both mental and even physical health issues, e.g., chronic-stress, or joint-pain. Instruments including the Tibetan singing bowl and vocal chanting, are still widely used today. With the noise-floor of modern urban soundscapes continually increasing and known to impact wellbeing, methods to improve this are needed. With that in mind, this study presents the Acoustic Sounds for Wellbeing (ASW) dataset. The ASW dataset is a dataset gathered from YouTube including 88\,+ hrs of audio from 5-classes of acoustic instrumentation (Gongs, Drumming, Singing Bowls, and Chanting). We additionally present initial baseline classification results on the dataset, finding that conventional Mel-Frequency Cepstra coefficient features achieve at best an unweighted average recalled of 57.4 % for a 5-class support vector machine classification paradigm.

EXPERIMENTAL SETTING As a first step for analysis of the classes within the ASW dataset we perform a series of baseline classification experiments:
-
[4]
2 Class: Gong (gon) vs. Singing Bowl (sb) - Given the sim- ilarity of these two instruments, such as the common use of materials (i. e., often precious metal), we choose this combina- tion to take a closer look at the difference in the data sources for these two classes
-
[5]
3 Class: Chimes (chi), Drum (dru), Gong - Counter to the 2 Class task, we choose this combination due to their intrinsic acoustic difference
-
[6]
e., most variety) and smallest class
4 Class: Chimes, Drum, Gong, Singing Bowl - In this experi- ment we remove the Chanting class, as this is the only human related audio sample, as well as the nosiest (i. e., most variety) and smallest class
-
[7]
5 Class: Chanting (cha), Chime, Drum, Gong, Singing Bowl - All classes of the ASW dataset together, should be seen as the official baseline for the ASW dataset. 3.1. Baseline Partitioning To partition the data into train, validation and test, we chose a data- independent schema. Ultimately this led to a slight imbalance be- tween classes due to the varied ...

RESULTS AN DISCUSSION Results from the various experimental setups, are give in Table 2. We choose unweighted average recall (UAR) as our evaluation metric due to the imbalance between classes. Overall the MFCC results are stronger for each classification scenario on the test set. Although it is negligible, we do see improve- ment from DEEP SPECTRUM on the...
