Новая проблема Audacity с новым FFMPEG, экспортирует 8 каналов в 7.1 и вырезается через 23 минуты. его 2-х часовые треки. Он идет к 1.x ближе к концу, много места на диске, не уверен, что с ним не так.Audacity FFMPG экспорт частичного файла

скопировать его и проверить продолжительность: 'FFmpeg -i - -с копии«F: \ Something.wav» ' – Mulvya

Тот же результат, 23 минут длина на аудио файл. – Wilken

Куда вы его прокладываете? – Mulvya

Полная выходная мощность, включая некоторые ошибки, но в конечном итоге отлично работает после присоединения к MKV. Я экспортировал каждый трек из дерзости, как отдельный файл, а затем использовал ffmpg присоединиться к ним, используя следующие опции
