Track head missing during playback 再生時、トラックの頭が欠ける

euNor · May 5, 2024, 8:40am

Pro Tools Carbonを使用しています。
再生時、デバイスのサンプリングレートと異なるファイルを再生した場合、デバイスのサンプリングレートが自動的に切り替わりますが、その際変更中にファイルの再生が開始されてしまい、トラックの頭が欠落することがあります。
サンプリングレートの変更を伴う場合に、1曲目のみ再生を少し遅らせるような設定は可能でしょうか。

Pro Tools Carbon is used.
During playback, if you play a file that is different from the device’s sampling rate, the device’s sampling rate will automatically switch, but the file may start playing during the change, resulting in a missing track head.
Is it possible to set the playback of the first song to be slightly delayed when the sampling rate is changed?

Hi @euNor,

You should look for this settings in the audio output settings in Audirvāna which can add latency during sample rate change:

euNor · May 6, 2024, 8:58am

Completely resolved. Thank you for your help!
Now that I know why I didn’t notice this setting, I’m going to share it for Audirvana.

As you noticed, I am Japanese, so I use it in Japanese settings, but there seems to be an error in the Japanese translation on the GUI.
I think “spl.” stands for sampling rate, but the person in charge of Japanese translation misunderstood this as “Sound Pressure Level” and indicated it as “音圧レベルレート”

According to the other items, it would be “サンプルレート変更時の追加レイテンシー”
