The pi audio jack stops at 15.000hz, because of the high pass filter and PWM limitations.Įven with a DAC board the raspberry pi4 is a bad choice for audio reproduction. All DAC boards and the sonos reproduce this range. The normal hearable audio range depending on your age is between 20hz and 20.000hz. Also the high frequencies are not reproduced at all.
The audio jack has a THD of 10% at 10kHz. A raspberry Pi DAC board about 0,08% at 10kHz.
A sonos you want to compare with has a THD of about 0,03% at 10kHz. Sound quality is often determined by total harmonic distortion. There are people who read this here and get very disappointed by the sound if they try this setup. Please investigate first, before writing such nonsense. Using the 3,5 jack and talking about sound is like driving a 40 years old fiat panda and comparing it to a new ferrari. There are PCM5122 based sound boards for about 20$ and this increases the pi sound quality VERY much. The sound is smeared and sounds very harsh and digital.īuying an inexpensive DAC board for the pi is the way to go if you want to compare it to the sonos for example. If someone does not hear this, go to a doctor. There is nothing else to say, look at measurements. The raspberry pi audio jack is a pwm driven output, no real DAC behind it. Of course there is a possibility to use the pi for this, but not with its audio jack. Comparing the audio jack from a pi with a sonos is just a joke. Hi, I ask myself if the person, who wrote this article ever tried this setup. If you already have a BalenaCloud account, login to BalenaCloud.
RASPBERRY PI PA SYSTEM BLUETOOTH
BalenaSound is pre-built with a lite client for music streaming via the Pi’s Bluetooth and eliminates the need for attaching a monitor, mouse, and keyboard to our Raspberry Pi.ġ. Instead of the standard Raspberry Pi OS, we will flash BalenaSoundOS to our microSD card.
If you have a non-bluetooth receiver with a 3.5mm jack input, you can connect your speakers to your receiver and your receiver to your Raspberry Pi. This is an excellent project for repurposing old receivers.Timing: Please plan for an hour to complete this project.You do NOT need a monitor, mouse, or keyboard for your Raspberry Pi in this project.We tested with multiple Raspberry Pi 3B+ devices, but were unable to find the bluetooth signal during testing for this project.The Pi 400 requires a USB speaker since it does not have an audio jack output. During the writing of this article, we found the Raspberry Pi 4 with a 3.5 mm audio input to be the best hardware setup.Speakers with 3.5mm audio input and/or receivers with 3.5mm audio input.8 GB (or larger) microSD card, U3 cards recommended (see best Raspberry Pi microSD cards).Raspberry Pi 4, or Raspberry Pi 400:one unit per room.
