Methods and apparatus for volume adjustment
Apparatus, systems, articles of manufacture, and methods for volume adjustment are disclosed herein. An example method includes collecting data corresponding to a volume of an audio signal as the audio signal is output through a device, when an average volume of the audio signal does not satisfy a volume threshold for a specified timespan, determining a difference between the average volume and a desired volume, and applying a gain to the audio signal to adjust the volume of the audio signal to the desired volume, the gain determined based on the difference between the average volume and the desired volume.
1. A computing system comprising:
a processor; and
a non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by the processor, cause performance of a set of operations comprising:
collecting data corresponding to a volume of an audio signal as the audio signal is output through a device;
determining an average volume value of the audio signal;
determining that a difference between the average volume value and a desired volume value is outside of a volume threshold; and
applying a gain to the audio signal to adjust the volume of the audio signal to the desired volume value, the gain determined based on the difference between the average volume value and the desired volume value.
2. The computing system of claim 1 , wherein the set of operations further comprises:
compressing the audio signal when media represented in the audio signal is unidentifiable prior to the audio signal being output through the device.
3. The computing system of claim 1 , wherein the set of operations further comprises:
buffering the audio signal to cause a delay in outputting the audio signal.
4. The computing system of claim 1 , wherein the set of operations further comprises:
applying a second gain to the audio signal to adjust the average volume value of the audio signal prior to the audio signal being output through the device.
5. The computing system of claim 4 , wherein the second gain is determined based on the average volume value of the audio signal.
6. The computing system of claim 1 , wherein the set of operations further comprises:
collecting the data for a threshold period of time.
7. The computing system of claim 1 , wherein the set of operations further comprises:
collecting the data over a threshold sample frequency.
8. A non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by a processor, cause performance of a set of operations comprising:
collecting data corresponding to a volume of an audio signal as the audio signal is output through a device;
determining an average volume value of the audio signal;
determining that a difference between the average volume value and a desired volume value is outside of a volume threshold; and
applying a gain to the audio signal to adjust the volume of the audio signal to the desired volume value, the gain determined based on the difference between the average volume value and the desired volume value.
