Note: These effects are only available on downloaded audio shows, occasionally a show isn't playable by the enhanced engine and under this circumstance RSSRadio7 will fall back automatically to iOS's built in AVPlayer. DSP effects are not available in fallback mode.
Where to find the DSP effectsAccess the DSP effects through the Settings option on the Now Playing screen; you can also fine them in the main Settings, Now Playing Settings.
EQThe equaliser option allows the frequency response of the sound to be finely tuned through a number of presets (the same as the iPod app). "Spoken Word" would be a common choice for most podcasts.
The EQ can be used on all types of Podcast.
Audio CompressorThe audio compressor makes quiet sounds louder, and loud sounds quieter. This can be particularly useful in noisy environments such as cars and trains or where different podcast presenters have very different volume levels.
Using the Audio Compressor on Music podcasts will produce strange effects and is not recommended.
Volume BoosterThe volume booster makes all sounds in the podcast louder, if a sound is already loud and amplifying it would produce distortion then the booster will hit a "limiter" and will not boost this sound. In this way it can be used to amplify only quiet parts of Podcasts without risking deafening you.
Using the Volume Booster on Music podcasts will produce strange effects and is not recommended.
Silence SkipSilence Skip is absolutely my favourite effect. Silence Skip will remove all of the pauses and silence from Podcasts, on most independently produced spoken word podcasts this can be around 10% of the total time.
Normally you won't be able to tell the difference with Silence Skip active, other than the time you are saving.
Silence Skip is a great alternative to 1.25x or 1.5x playback and can be used on any kind of Podcast.
On very rare occasions Silence Skip can make it seem like the volume of the podcast is varying up and down, normally turning on the Audio Compressor negates this effect.
Leave Silence skip on all the time.
DSP Effects and Battery LifeThe DSP effects are generally more work for your device, therefore its a logical to conclude that they will use a little more battery power.
The DSP effects are highly optimised and any extra battery drain won't be noticed. In fact with the Silence Skip it can end up saving battery as the total playback time is reduced.
