I found Pimsleur's German Phase 1 very easy to use and understand. The format is excellent. It eases you into the language and through continuous repetition plants the language in your long term memory. The repetitiveness is by no means tedious and the course constantly challenges you to think for yourself by forming sentences from the vocabulary you have learned. It does not overload you either with information but instead gradually introduces additional vocabulary. The tutor goes back on previous units as a refresher every so often which ensures that earlier lessons are not forgotten. I would recommend this method of language learning and look forward to starting lessons 6-10.
This is easily the most comprehensive audio-only course I have been able to find. This version from Audible is the 3rd edition of a very fine programme that has been around since the mid-nineties but this edition is a big improvement on the original -- and at a far lower price. I worked through Phase 1 from the earlier version and thoroughly enjoyed it as I always felt I was easily making good progress, I am now halfway through Audible's Phase 2.
There are 4 Phases, the first three consist of 30 half-hour lessons which give the student a considerable amount of time to practice his newly-acquired language skills. Phase 4 contains ten more 30 minute lessons to polish up everything he has learned. would think that by the end the student will be able to travel through Germany and Austria easily and be able to converse with people with relative ease.
The only other audio course to rival this one is the Michel Thomas Course -- but I much prefer this one
