A frequent concern of listeners is the site's policy of allowing any recording to be published as long as it is basically understandable and faithful to the source text.[17] This means that some recordings are of lower audio fidelity; some feature background noises, non-native accents or other perceived imperfections in comparison to professionally recorded audiobooks.[18][19] While listeners may object to those books with chapters read by multiple readers,[20] others find this to be a non-issue or even a feature.[21][22][23]
