数字化改变了流音乐广播。来自Spotify和iTunes等音乐流媒体服务的竞争在很大程度上超过了传统的播放列表电台,上世纪90年代,公共服务电台通过软件生成的播放列表在全球范围内的传播,已经取代了热情的音乐电台主持人。但数字化也改变了我们研究无线电的方式。在丹麦,从1989年开始,几乎所有的广播节目都进行了数字化,这使得人们能够真正聆听这些档案,来研究广播内容的历史变化。本文通过定性案例研究与新的大规模研究相比较,探讨了丹麦广播公司(Danish Broadcasting Corporation) P3广播频道1989-2019年音乐与谈话的分布情况。从方法论上讲,这种从近距离收听少数节目到远距离收听超过65,000小时的广播的转变,使我们能够对两种分析的方法、结果、优缺点进行讨论和批判性比较。先前的研究已经证明,用于音频频谱图像识别的卷积神经网络(CNNs)优于其他方法,如支持向量机(svm)。提出的大规模研究表明,基于cnn的方法可以很好地概括丹麦广播的语音和音乐分类,即使没有微调,总体准确率达到98%。
