И Windows 10, и Windows 11 обладают крайне аскетичным набором функций, когда речь заходит о передаче звука по Bluetooth. Штатными средствами определить используемый операционной системой Bluetooth-кодек не получится, тем более не получится найти где-либо в интерфейсе Windows кнопку «поменять кодек». В этой статье мы разберемся, каким образом можно определить активный кодек, а также рассмотрим способы переключения и изменения параметров Bluetooth-кодеков в Windows.

Картинка с сайта: www.ixbt.com

Содержание

• Какие кодеки поддерживает Windows
• Как увидеть используемый кодек
• Как поменять выбранный системой Windows кодек
  • • Как переключить Windows 11 с AAC на aptX (бесплатно)
    • Как добавлять / модифицировать кодеки и переключаться между ними (платно)
• Повышаем битрейт SBC до 600 кбит/с и выше (SBC-XQ)

Windows 11 нативно поддерживает кодеки SBC, aptX и AAC, также в этом году в свежих устройствах начала появляться поддержка кодека LC3. В Windows 10 реализована поддержка SBC и aptX, а AAC доступен в инсайдерских билдах. При выборе кодека Windows 11 отдает предпочтение AAC. Если подключаемое устройство не поддерживает данный кодек, тогда выбор падает на aptX, а SBC является кодеком «последней надежды».

Windows 10 предпочитает aptX, а SBC является запасным вариантом. Также существует способ подружить Windows 10/11 с кодеками aptX HD, aptX Low Latency и LDAC, но об этом чуть позже.

Чтобы понять, какой Bluetooth-кодек использует Windows для передачи аудио, устанавливаем программу Bluetooth Tweaker. Это платное ПО, но в течение 7 дней можно пользоваться бесплатной демоверсией.

Картинка с сайта: www.ixbt.com

В окне программы мы видим перечень кодеков, с которыми может работать конкретное устройство (в данном случае наушники Razer Opus), а также тот кодек, которому отдала предпочтение Windows (в моем случае AAC 256 кбит/с).

Обычный кодек SBC сегодня мало кто считает лучшим решением для беспроводной передачи аудио. «Модифицированный» SBC, он же SBC-XQ — совсем другое дело, но об этом речь пойдет позже. Итак, большинство пользователей Windows 10 используют aptX, если их наушники его поддерживают, или SBC, если нет. Тут никаких проблем. А вот Windows 11 обычно предпочитает кодек AAC, да зачастую ещё и со сравнительно низким битрейтом в 256 кбит/с (вместо максимально возможного для этого кодека 320 кбит/с), в то время как на aptX можно получить более солидные 384 кбит/с.

Пользователь reddit с никнеймом BugMuzzy нашел бесплатный способ переключения кодека в Windows 11 через редактор реестра.

• Для начала следует убедиться, что ваша модель наушников сама по себе поддерживает кодек aptX, в противном случае после выполнения следующих действий Windows 11 будет использовать кодек SBC.
• Открываем редактор реестра и переходим по пути HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BthA2dp.

Картинка с сайта: www.ixbt.com

• Создаем раздел Parameters (если его нет по указанному пути) и в нем создаем параметр BluetoothAacEnable, которому присваиваем значение 0. После этого в настройках Windows выключаем и обратно включаем Bluetooth, заново подключаемся к наушникам (или другой используемой акустике), и теперь вместо AAC будет использоваться кодек aptX. Убедиться в этом можно с помощью упомянутой ранее утилиты Bluetooth Tweaker.

Следующий способ связан с использованием альтернативного драйвера A2DP от создателей Bluetooth Tweaker. Он также поставляется с 7-дневным триалом, так что оценить все его прелести можно и бесплатно, но для продолжительного использования понадобится приобрести лицензию.

Что умеет этот альтернативный Bluetooth стек:

1. Добавляет поддержку кодеков aptX HD, aptX LL и LDAC;
2. Позволяет в любое время переключаться между любыми кодеками отдельно для каждого устройства воспроизведения;
3. Позволяет менять различные параметры для каждого из кодеков (см. скриншоты), что особенно важно для SBC и LDAC.

Также альтернативный драйвер автоматически переключает кодек AAC в вариант с битрейтом 320 кбит/с. В моем случае Win 11 использовала AAC 256 кбит/с, в то время как наушники поддерживают и 320 кбит/с. После установки альтернативного драйвера битрейт автоматически увеличился до 320 кбит/с. В этом можно убедиться с помощью утилиты Bluetooth Tweaker, см. скрин ниже.

Картинка с сайта: www.ixbt.com

Едва ли не самая «вкусная» функция альтернативного драйвера A2DP — это возможность гибко настраивать кодек SBC, превращая его в достойную альтернативу aptX HD или даже LDAC. Переопределяя битпул, можно поднять битрейт кодека SBC до значений свыше 1000 кбит/с и улучшить качество звука в устройствах, не имеющих поддержки современных «премиальных» кодеков.

Картинка с сайта: www.ixbt.com

Следует понимать, что чем выше установленный битрейт, тем хуже стабильность сигнала в сложных условиях. Здесь всё зависит от конкретного сетапа, и у некоторых юзеров получается на практике использовать SBC с битрейтом 1100 кбит/с. В целом оптимальным по качеству звука/стабильности сигнала для SBC-XQ принято считать значение 551 кбит/с либо 600 кбит/с (в зависимости от частоты дискретизации — 44.1 кГц либо 48 кГц) в режиме Dual Channel. О причинах этого можно почитать в обстоятельной статье на Хабре.
