Abstract: A computer-implemented method performed by a data processing apparatus includes receiving an audio signal that includes a frequency-domain representation of an audio file, extracting, from the audio signal, a plurality of frequency-domain data values that correspond to at least a portion of the audio file, compressing the plurality of data values to form a compressed frequency domain value file, and transmitting the compressed frequency domain value file to a server to identify the audio file.

Abstract: Systems and techniques are provided for finding differences in nearly-identical audio recordings. A first version of an audio recording may be received. A second version of the audio recording may be received. A difference between the first version of the audio recording and the second version of the audio recording may be determined using time domain analysis and frequency domain analysis. The difference may be stored in a difference set. The difference set may allow the first version of the audio recording to be distinguished from the second version of the audio recording. The audio recording may be a music track. The first version of the audio recording may be an explicit version of the music track. The second version of the audio recording may be an edited version of the music track.
Abstract translation: 提供了系统和技术，用于发现几乎完全相同的音频记录的差异。 可以接收第一版本的音频记录。 可以接收第二版本的音频记录。 可以使用时域分析和频域分析来确定音频记录的第一版本和音频记录的第二版本之间的区别。 差值可以存储在差值集中。 差异集可以允许音频记录的第一版本与音频记录的第二版本区分开。 音频记录可以是音乐轨道。 音频记录的第一版本可以是音乐轨道的显式版本。 音频录制的第二版本可以是音乐曲目的编辑版本。
