# 2019年Freesoundオーディオタギング用の前処理済みオーディオ
このコンペティションはカーネルのみのコンペです。カーネルの実行時間内でできることを最大化するために、時間を節約したいと思います。このデータセットはメルスペクトログラムとして前処理されたファイルを提供します。
# _バージョン2 新_
前処理パラメータを以下のように修正しました。変換されたメルスペクトログラムは、バージョン1から半分の長さになりました。サイズ128x128は1秒の音声でしたが、現在は長さ128で2秒になります。この変更は基本的にバグ修正です。なぜなら、持続時間が2秒に設定されている場合、128x128は2秒であるべきだからです。これにより基本的にパフォーマンスが向上します。
conf.sampling_rate = 44100
conf.duration = 2 # 秒
conf.hop_length = 347*conf.duration # <==== `conf.hop_length = 347` から更新
conf.fmin = 20
conf.fmax = conf.sampling_rate // 2
conf.n_mels = 128
conf.n_fft = conf.n_mels * 20
# 内容
すべてのトレーニング用の精選データ、ノイジーデータ、テストデータについて、3つのファイルをピクル化しました。
